National Cancer Control Plans (NCCPs) are overarching strategic frameworks developed by governments to establish priorities for cancer, including:
- Prevention
- Diagnosis
- Treatment
- Survivorship
- Palliative care
Crucially, their potential to drive meaningful improvements in cancer outcomes has been proven.
Prevention is a glaring omission
The International Cancer Control Partnership’s most recent global review of NCCPs found that only 30% of all cancer plans address prevention. This is a glaring omission, especially given that the cancer burden is already unsustainable – placing increasing pressure on over-stretched health systems and economies. Nearly half (40%) of all cancer cases are preventable by addressing modifiable risk factors including diet, weight, activity, alcohol, smoking and sun exposures, underscoring the fact that prevention is the sustainable way forward.
World Cancer Research Fund are on a mission to wave the flag for primary prevention. First off, Rachael Gormley, acting president of World Cancer Research Fund International, took part in a roundtable event about NCCPs at the recent World Economic Forum in Davos, Switzerland. Rachael took full advantage of this important platform to emphasise why prevention must be central to all cancer strategies.
We also welcomed the UK government’s call for evidence on the National Cancer Plan for England. Our primary goal is to ensure that the new plan places prevention and survivorship at its heart. We’ll be sharing our written submission in due course and look forward to collaborating with organisations across sectors to amplify our calls.
Plans can be force for positive change
The International Cancer Benchmarking Partnership has examined the relationship between cancer policies and survival rates. It found significant potential for NCCPs to improve cancer diagnosis, treatment, and outcomes when applied strategically and successively.
Countries that adopt this approach have experienced the greatest improvements in cancer survival. For example, Denmark, which implemented 4 consecutive plans between 2000 and 2020, has significantly improved the survival rates for multiple cancers, including an 19% increase in the 1-year survival rate for lung cancer over 15 years.
Prevention is crucial to the success of NCCPs as it offers the most effective and affordable long-term method of cancer control. Prevention policies range from interventions aimed at reducing risk factors, such as helping smokers quit, and policies to reduce overweight and obesity, to actions that tackle cancer-causing infections, such as human papilloma virus vaccination programmes.
While NCCPs are not a silver bullet, they present a unique opportunity to implement targeted, context-specific actions on a national scale. This is particularly important for prevention, where wide-ranging strategies can benefit from the streamlined and coordinated structure of NCCPs, which can set out a roadmap of action across the entire prevention continuum.
Bottom line is rising cancer burden
The growing global cancer burden is why NCCPs focused on prevention are needed.
The WHO estimates that nearly 1 in 6 deaths globally are caused by cancer each year, meaning that annually around 10 million people lose their lives to cancer. The latest statistics on global cancer rates also show that in 2022, there were 20 million new cancer diagnoses, and 53.5 million people living with or beyond cancer.
The enormity of these figures can make it difficult to remember that they represent real people who have had their lives turned upside down by cancer.
It isn’t only the human cost of cancer that is immense. The social and economic costs are also undeniable, making it particularly concerning that globally new cases are expected to skyrocket to 35 million annually by 2050. This increase will be felt most acutely in low- and middle-income countries, which are expected to experience a more rapid rise in cancer rates in the coming decades.
Fortunately, this worrying trajectory is not inevitable. A focus on cancer prevention in NCCPs would allow millions more people to live cancer free. It is also the most cost-effective way to tackle cancer and, crucially, reduces the need for expensive later stage treatments that are often inaccessible to many. In addition, it could lead to an array of co-benefits such as the prevention of other non-communicable diseases and a reduction in health inequalities.
While this shift to prevention requires systemic change coupled with sustained investment, the challenge is not insurmountable. Ultimately investment in prevention will have the highest pay off for governments and the good news is that we already know the integrated policy approach needed to make this a reality.
NCCPs are a meaningful tool to prevent cancer and improve survivorship, support health systems, and promote economic growth. We will continue making the case for prevention to ensure that NCCPs fulfil their potential to reduce the cancer burden. Alongside working to ensure the National Cancer Plan for England prioritises prevention, we will be calling for all countries to develop NCCPs that include meaningful prevention measures at the UN High-Level Meeting on non-communicable diseases in September.
The UK’s National Day of Reflection takes place on 9 March 2025, as an opportunity to come together to remember those who died as a result of the COVID-19 pandemic, and to honour the tireless work and acts of kindness shown during this unprecedented time.
World Cancer Research Fund are proud to be involved in this day and extend it into an opportunity to remember all of those we love who have died. We know many of our fantastic supporters welcome our innovative and groundbreaking work in memory of someone special.
Remembering Mary Towsey
Mary’s family kindly shared this tribute to her, as a supporter of World Cancer Research Fund.
Born in Epsom on 24 July 1936 to Freda and Norman Prideaux, Mary grew up in a loving household with her younger sisters, Jane and Jill. After the war, they all settled into what was to become a bustling, lively, family home in Hampshire filled with grandparents, friends, dogs, cats, geese, heifers, chickens and, most importantly, love and laughter.
Her favourite expression was “Find a way, make a way”. She could make something from nothing, whether an impromptu meal or a beautiful and cosy room in her house. She often saw beauty where others didn’t, and had a gift for showing others the world through her eyes.
Mary started her own very successful art school in Cobham, Surrey, where she would share her skill and knowledge with many aspiring artists. As was so typical of her, she often said she learned as much from her students as they did from her.
When she finally retired from teaching and moved to a smaller house, Mary continued to paint, having made a small studio in her attic, and she continued to socialise with her many friends. Still being full of energy and wanting to do more, she started going to a Pilates class for the more mature woman. There she met a lovely group of women with whom she spent most of her time laughing.
In her quiet moments, Mary would enjoy sitting in her conservatory, drinking coffee while watching the birds feast from the bird table. Mary was an active person, filled with energy who kept gardening and painting until the end of her life.
World Cancer Research Fund is humbled to receive gifts in memory of special people, like Mary.
We have a tailored in memory programme where we supply forget me not seeds in the spring, and memorial baubles at Christmas, as well as online ways to share your loved one’s life. Visit Give in memory for more information.

The term “plant-based diets” has become popular in recent years. These types of diets, which are traditional for some parts of the world (eg in Asia and the Mediterranean region), are rich in vegetables and fruits, plant oils (mainly olive oil), and fish, but consumption of meat and dairy products is traditionally low. Numerous studies have shown that these types of diets are beneficial for human health.
On the other hand, diets of affluent western societies have changed significantly during the past 60 years towards a diet that is rich in meat, refined carbohydrates, sugar, and saturated fats. This type of diet is not only associated with a higher risk of chronic diseases such as cardiovascular diseases, diabetes and several types of cancer, but it also has a strong impact on our planet’s climate.
Production of animal products such as meat and dairy needs more energy than the production of plant products, hence, by reducing our consumption of animal products, we can save significant amounts of energy. For example, in Switzerland, about 30% of environmental impacts are due to food production, transportation and consumption (PDF).
An international group of nutrition scientists has proposed a diet that meets most nutrition requirements, while simultaneously taking sustainability and planetary health into account. This diet is often called the “EAT-Lancet Reference Diet” or “Planetary Health Diet”. It’s mainly plant-based, meaning that carbohydrates come from whole grains, proteins are mainly from legumes (such as beans, lentils, peas, but also soy food and peanuts), and fats are mostly unsaturated plant oils. Animal products are not forbidden, but their consumption is recommended to be limited.
Our research group at the University of Zurich, in collaboration with colleagues from other universities, was interested as to whether this type of diet, which is thought to reduce the damaging impact of food on our environment, also has beneficial effects on our health, particularly regarding the risk of cancer.
To try to answer our question, we needed a dataset in which the food consumption of the participants was assessed, but in which participants were also followed up for a number of years so that we could know how many of them were diagnosed with cancer. The UK Biobank is a large cohort in the UK that includes more than half a million people. Using data from this large cohort, we have examined how closely people were following the recommendations of the EAT-Lancet Reference Diet in 2005–07, and how many of them had been diagnosed with cancer until 2019.
Sustainability lowers cancer risk, too
When we compared those participants whose diet was closest to the EAT-Lancet Reference Diet with those who ate a less sustainable diet, we saw that an environmentally friendly diet was indeed associated with a lower risk of cancer. Better adherence was linked to a 10% lower cancer risk. However, we did not see a particularly strong protective effect for a specific type of cancer.
The results of our study are consistent with those of other groups trying to answer the same research question using different data sets. This strengthens our conclusions that a planet-healthy, plant-based diet can promote health.
In fact, plants are excellent sources of most of the essential vitamins and minerals in our diet. When a plant-based diet is balanced, products of animal origin are only needed in moderation to provide us with the few essential vitamins that cannot be found in plant sources (eg vitamin B12).
Greater focus should be given to exploring different plant-based foods, as well as on how to prepare plant foods – in particular legumes – so that more people are able to cook and enjoy these types of foods. Consumers, researchers and cooks need to team up to develop climate-friendly recipes. In Switzerland, we have published the first cookbook that only contains climate-friendly recipes. And recently World Cancer Research Fund developed Budget-friendly recipes: Good for you, good for the planet.

Siobhan McGeown
Siobhan was inspired to run by her parents (in main picture), who have both had cancer. She says: “After watching both my parents suffer from cancer (ovarian and prostate), as well as several other close family members, I want nothing more than to see better outcomes for cancer diagnoses, as well as better detection and testing before it gets to that stage.”
Angela Brooks (left, wearing cap)
Angela was diagnosed with breast cancer in 2021 aged only 33. She’s currently in remission but still living with the impact of cancer, including early menopause. Angela told us about her training schedule: “Every 3 weeks, between rounds of chemotherapy, I set myself the goal of completing a 10k run.”
Sam Burton
Sam says: “The decision to run for World Cancer Research Fund is driven by my Father’s recent diagnosis with kidney cancer, an event that has reshaped my perspective on life and illuminated the critical importance of cancer research and advocacy.”

Jack Gibbons
This is Jack’s second marathon for us, having also run in 2018. He’s running in memory of his mum, Maggie, who received a diagnosis of very aggressive stage IV melanoma in late 2023 and passed away in January 2024.
Maggie was there to support Jack when he ran his first marathon and was there at the finish line of the London Landmarks half in 2023 to see him over the line. Her support meant the world to Jack and he’s proud to be able to run for her in 2025 and raise money for World Cancer Research Fund.
David Herlihy
David sadly lost his Dad to cancer in April 2024, and his Mum has been diagnosed with cancer for the second time in 5 years. He’s dedicated to health and fitness, and has completed 5 marathons, an ironman and 2 ultra marathons.
Hannah Stedman
Hannah is running in memory of her amazing Mum, who “had a very quick battle with lung cancer in October 2023. She was diagnosed on the 3rd and had passed by the 24th. To say this experience was the hardest thing of my life is an understatement.”
George White
George is a mortgage broker based in the West Midlands and is motivated to run for us after recently losing his Godfather to cancer.
Obesity is a public health emergency with England having one the highest rates among high-income nations.
There are stark inequalities in this country across the ages, geographic areas, genders, ethnic groups and for those with both mental and physical disabilities.
And these inequalities are growing, as rates of children with obesity are increasing significantly faster in communities with high deprivation levels compared to those with low deprivation levels.
And yet when the UK government has the chance to make a difference it is missing the mark.
They recently responded to the House of Lords Committee report entitled Recipe for Health, which set out realistic and transformative recommendations to improve the nation’s diet.
But we were disappointed to see their tepid response with the UK government listing their existing commitments rather than giving a clear signal that they would adopt any of the report’s recommendations.
This raises serious concerns about whether their upcoming National Food Strategy will turn out half-baked.
At World Cancer Research Fund, we want to see bold government policies in cancer prevention and nutrition.
This includes mandatory targets to improve nutritional quality of food, an expansion of the Soft Drinks Industry Levy to unhealthy foods as well as a strengthening of its sugar threshold, and the introduction of a mandatory front-of-pack labelling scheme.
The government must also ensure that the upcoming marketing restrictions on unhealthy foods are enforced without delay.
There is no doubt that the government wants to put prevention policies at the heart of what they do – they set it out clearly in their manifesto.
But with around 40% of cancer cases being preventable, they need to go further and faster on improving the nation’s diet – they need to take up the recommendations in the Recipe for Health report.

Our Cancer Prevention Recommendations
Experts now believe that up to 40% of cancer cases are preventable. These are a blueprint for how to reduce your risk of cancer
At an event to mark World Cancer Day, the Health and Social Care Secretary, Wes Streeting, announced the development of a National Cancer Plan for England.
He also launched of a new, world-leading trial that is testing AI tools to diagnose breast cancer cases earlier. More than 700,000 women are expected to take part.
Breast cancer is the most common type of cancer in women, with more than 59,000 people being diagnosed in the UK in 2021.
Alongside this, Streeting announced a new initiative called the UK Collaborative for Cancer Clinical Trial Research, which will help to maximise opportunities for the UK to lead in clinical research.
It is being hosted by the Association of Medical Research Charities, of which World Cancer Research Fund is a member.
Responding to the launch of the Government’s consultation on the National Cancer Plan for England, World Cancer Research Fund’s Executive Director of Research and Policy Dr Giota Mitrou, said:
“Around 40% of cancer cases can be prevented by making our lives and the environment we live in healthier.
“We therefore warmly welcome the UK Government’s consultation on the National Cancer Plan for England and commitment to publishing the Plan this year. Marking a pivotal opportunity to shift the dial from sickness to prevention, the Government must ensure the Plan is truly transformative and achieves a step change in cancer prevention so that more people can live free of cancer.
“The launch of a new UK Collaborative for Cancer Clinical Research also provides a welcome focus to maximise opportunities for cancer research. As a member of the Association for Medical Research Charities leading this work, we stand ready to share our expertise on research in cancer prevention and survivorship.
“Overall, the Government’s announcement is a huge step in the right direction. We look forward to working with the Health Secretary and others to make the Plan a reality.”

Despite the advances in cancer research over the past 40 years, including World Cancer Research Fund’s evidence on cancer prevention, and dramatic advances in cancer treatment, one question remains to be answered: why does one person get cancer when another, who lives a similar lifestyle, does not?
Experts estimate that up to 40% of cancer cases are preventable, if people didn’t smoke, avoided the sun, avoided alcohol, ate a healthy diet, maintained a healthy body weight and stayed physically active. But that doesn’t mean we can reduce our own risk of cancer by 40% if we follow this advice. It’s not easy to estimate an individual’s cancer risk because so many biological and genetic factors are also at play.
And that’s where large databases about our health can make a big difference. One of these is the UK Biobank, which contains details about the health – and increasingly, as the participants get older, the ill-health, of 500,000 people in the UK. The longevity of this data – not just at one point in a person’s life but repeatedly measured over a long period of time – helps us understand what influences cancer risk throughout someone’s life.
Heel bone density to house size
Since 2006, the UK Biobank has been collecting environmental, lifestyle and genetic information about the participants. For scientists, the size, range of information – from heel bone density to blood pressure to the size of their house – and duration of information collected is a gold mine.
It has been described as “the world’s most important health database” yet it’s not the only resource of this type. Another large database established as part of the European Prospective Investigation into Cancer and Nutrition (EPIC) study has grown into a massive project involving 10 countries, with 521,000 participants and data collected over more than 30 years.
Of the 30,000 registered researchers from 100 countries who have used data from the UK Biobank, some are funded by the World Cancer Research Fund network, and are using the data to investigate a range of cancer risk factors:
- Sleep, sleep patterns, and risk of prostate and endometrial cancer
- Fat tissue and advanced prostate cancer risk
- Social inequality and cancer risk
- Physical activity, sedentary behaviours, and cancer, cardiovascular disease and diabetes
- Plant-based diets
- Ultra-processed food
- Following our Cancer Prevention Recommendations
- Obesity and insulin
- Vegetarian diets
- Links between diabetes and cancer
- How many cancers are linked to obesity and physical activity?
Some of the things our scientists have found out using UK Biobank data include:
- Physical activity across the day – with a peak early in the morning and late in the evening – linked to lower risk of colorectal cancer
- Ultra-processed food increases cancer risk
- Following our Cancer Prevention Recommendations reduces the risk of all cancers
The UK Biobank allows researchers around the world to look at biological and medical data and “supports a diverse range of research intended to improve the prevention, diagnosis and treatment of illness, and the promotion of health throughout society”.
And it’s not easy to get hold of such large amounts of data. It’s hard to get half a million people to consent to sharing their personal data in this way, and even harder to get them to keep filling in surveys and undergoing procedures over many years. This type of research can only be done with people’s support and willingness to consent, and without it, finding ways to prevent and treat diseases such as cancer will be so much harder.
The wealth of data the UK Biobank contains could have drastic implications for cancer research, perhaps even finally helping realise World Cancer Research Fund’s ambition of living in a world where no one dies of a preventable cancer.
What do our grant holders say about UK Biobank?
Prof John Mathers
The scale, rich detail of participant characteristics and behaviours, and robust long-term information on health outcomes make UK Biobank a world-leading resource for studies of many aspects of nutrition and health including cancer risk and survival.
Dr Emma Allott
Whole body imaging data available in UK Biobank has enabled our team to measure the amount of fat surrounding the prostate in a large number of cancer-free men. These men are followed over time by the UK Biobank, giving us the opportunity to explore how the quantity of this fat type is related to future risk of prostate cancer. Studies like UK Biobank are critical for this type of research as the imaging required to measure this fat type is not otherwise available in healthy individuals. The results of our study will provide the first evidence for or against periprostatic fat as a risk factor for aggressive prostate cancer.
Dr Dagfinn Aune
We are using the UK Biobank to study the association between adiposity and physical activity and cancer risk. The very large sample size and the detailed assessment of adiposity measures, physical activity, other risk factors and a range of biomarkers are of major importance for our analyses. All this information helps us study associations with a range of cancer outcomes as well as exploring potential biological mechanisms that may explain or contribute to cancer development.
Dr Fiona Malcomson
Our studies using UK Biobank data have shown that people who adhere more closely to the WCRF/ AICR Cancer Prevention Recommendations have lower risk of developing cancer and, specifically, lower risk of cancer of the breast, bowel, kidney, oesophagus, ovary, liver and gallbladder. UK Biobank data has also enabled us to identify lifestyle and dietary patterns according to sociodemographic factors that will help guide public health strategies for cancer prevention.
The International Agency for Research on Cancer estimates that, by 2050, the world will see 35 million new cancer cases each year, up by 15 million annual cases in 2022. Yet with the right policies to prevent cancer, 14 million of those people could avoid their diagnosis. These policies would need to address a variety of factors, including tobacco, alcohol, overweight and obesity, breastfeeding and unhealthy diet.
Cancer places increasing burden on society
As the cancer burden increases, the strain on our health systems, economies and families becomes harder to meet. Unhealthy weight – just one risk factor – is projected to cost the global economy more than $4 trillion a year by 2035. Our food systems make eating a healthier diet harder. High production and consumption of red and processed meat, and low consumption of wholegrains, vegetables, fruit and beans, plays a role in increased cancer risk and the risk of other diseases such as diabetes. This misalignment also contributes to unhealthy natural environments, as diet-related greenhouse gas emissions are significant contributors to global warming. Most of these are related to production of animal-based foods. This is why prevention is the only sustainable way forward – with resilient populations and food systems working together for public health.
Prevention the sustainable way forward
We believe that prevention must be prioritised and is the only sustainable way forward. We also need to better explain:
- The science around cancer risk and diets, weight, breastfeeding, physical activity, and alcohol – as summarised in our Cancer Prevention Recommendations.
- Which policies should be prioritised to shape healthier environments that minimise these cancer risks for populations.
- How cancer prevention policy can have positive cascading effects for our health, but also for our health systems, our societies and our shared natural environment.
Cancer prevention policies can have ripple effect
We also know that cancer prevention policies can touch on and improve other areas beyond health. For example, diets high in red and processed meat increase people’s risk of colorectal cancer, and that healthier diets made up of more wholegrains, fruit and vegetables can protect people from the same type of cancer. This is why our Cancer Prevention Recommendations say people should limit red and processed meat, and eat a diet rich in wholegrains, vegetables, fruit and beansAt the same time, if our food systems produced less red and processed meat, and animal- food in general, and instead moved towards producing plant-based foods, this would have a significant impact in lowering diet-related CO2 emissions. Policymakers need to make sense of these connections, and our guidance shows what they need to do to promote such positive cycles – or co-benefits.
Why we created the Blueprint
Our well-established Cancer Prevention Recommendations cover 10 ways in which individuals can minimise their risk of preventable cancers. A growing body of evidence is showing that adherence to these Recommendations is associated with lower risk of developing cancer and other NCDs, but also lower risk of dying from cancer.
However, the Recommendations have not – until now – been presented alongside population-level policy advice. We need to promote an integrated approach to preventing cancer, otherwise policymakers may risk formulating repetitive but disconnected policy strategies across these areas that do not speak to or build on each other. For example, marketing restrictions can be a useful tool to encourage healthy diets but are also relevant for promoting breastfeeding and limiting alcohol consumption. Even though the targeted products are different, there are lessons to be learned from policy efforts across different cancer risk factors.
By joining the dots in these different areas, we can create greater awareness of how different policy approaches can contribute to cancer prevention. Our new blueprint makes a compelling case for action, especially for prevention to be included in national cancer plans. The blueprint also reinforces the need for a whole-of-government approach that puts public health goals before commercial interests.
What’s inside the Blueprint?

The Blueprint is accompanied by factsheets on specific cancer risk factors.
Our policy blueprint makes the case for population-level policy action and focuses on 5 factors: diet, weight, breastfeeding, physical activity and alcohol – in line with our Cancer Prevention Recommendations. We also look at how these factors can support people living with and beyond cancer
Our blueprint is an essential, evidence-based guide for policymakers and advocates, pulling together tools and resources to provide a comprehensive resource on cancer prevention. It pulls together existing tools and resources to support efforts on cancer prevention, including key guidance for World Health Organization, but also our existing NOURISHING nutrition and MOVING physical activity policy frameworks. All this information is distilled in a package of resources:
- An outline of 8 policy areas – including marketing restrictions, fiscal and legal, procurement, planning and incentives in communities– and how they apply to diet, weight, breastfeeding and physical activity.
- 10 factsheets with in-depth technical detail on how to roll out each Recommendation at population level.
- An exploration of the co-benefits of cancer prevention policy: addressing health inequities; meeting climate and sustainability targets; addressing commercial determinants of health; and fulfilling human rights.
- 7 strategies to help policymakers take action.
The goal of these resources is to strengthen understanding of how environment shapes cancer risk, and what policymakers can do about it.
How it was developed
To develop these resources, we built on our policy work, we reviewed existing key policy documents, and asked experts in the science and policy of cancer prevention, as well as lawyers, advocates for non-communicable disease prevention or breastfeeding what is most important in their respective areas. We then brought all the main elements together.
What’s next?
The Policy blueprint for cancer prevention will now be a centrepiece of our conversations with policymakers going forward – from Member States at the World Health Organization to the UN High-Level Meeting on Non-communicable diseases.
We invite you all to get involved: download the blueprint, share it, and use it in your work.

Eating a wide variety of food may reduce the risk of gastrointestinal cancers, according to research funded by the World Cancer Research Fund network* and published in the European Journal of Cancer.
Little is known about how eating a wide variety of food species, also known as food biodiversity, may benefit our health or affect our cancer risk. Food species refer to a distinct type of plant or animal, such as wheat, chicken, or salmon. For example, salmon, mackerel, and tuna are all separate food species, even though they share some biological traits and belong to the same food group. Similarly, rocket, lettuce and spinach count as separate food species, even though they are all leafy green vegetables. However, chicken and a chicken’s egg belong to the same food species even though they are different types of food.
This study is the first to examine how the number of different food types consumed, measured as Dietary Species Richness (the number of species an individual consumes per year) affects the risk of the following gastrointestinal cancers:
- Oesophagus
- Throat
- Stomach
- Bowel
- Colon
- Rectum
- Gallbladder
- Pancreas
- Liver
The study followed 450,111 cancer-free adults in 9 European countries from the European Prospective Investigation into Cancer and Nutrition cohort for 14 years. The researchers, from the International Agency for Research on Cancer, found that individuals with the most diverse diets, by including more food species in their diet, had a 23% lower risk of developing gastrointestinal cancers compared with those with the least variety. The risk decreased by 6% for every 10 extra species per year added to their diet. People can do this by including more variety in the types of fruit and vegetables they eat, for example, choosing to eat local and seasonal fruit and vegetables of different colours.
Food biodiversity includes eating different types of food that provide the necessary nutrients for maintaining health. Investigating food biodiversity is important because it has the potential to benefit public health and sustainable food systems.
Dr Helen Croker, our Assistant Director of Research and Policy, said: “Diets have become more limited in the types of foods eaten and they are often high in fat, sugar and salt. However, for cancer prevention, it’s important to eat a healthy, balanced and varied diet with plenty of wholegrains, pulses, vegetables and fruit.”
Dr Helen Croker
This study is particularly interesting because it looks at the number of different foods people eat and the impact it can have on their cancer risk, in particular gastrointestinal cancers. More research is now needed to confirm these findings and further explore the link between dietary diversity and cancer prevention.
Dr Inge Huybrechts
This study shows how a more diverse diet, including a large variety of species, could lower the risk of gastrointestinal cancers, emphasising the importance of eating a wide variety of foods. The idea behind a diverse diet consisting of many types of plants and animals species may provide essential nutrients for the body while also strengthening ecosystems, making them more resilient, productive, and sustainable.
Another study from this grant looked at how food biodiversity is measured. Methods such as Hill numbers estimate the number of species, but it wasn’t clear whether these numbers could be compared across different study settings.
The findings showed that Dietary Species Richness is the most feasible way to measure and evaluate food biodiversity across various contexts, and considering high-, middle- and low-income countries. Regardless of which Hill number was used, however, all measures indicated that greater food biodiversity was associated with better micronutrient sufficiency and with lower rates of all-cause mortality, this latter association yet being strongest for Dietary Species Richness.
This grant was funded by Wereld Kanker Onderzoek Fonds based in the Netherlands, as part of the World Cancer Research Fund International network.

Achieving a balanced combination of exercise and controlling our waistline is far more effective in reducing our risk of cancer than doing just one or the other, according to a study funded by World Cancer Research Fund.
In the world’s first study looking at the effectiveness of combining these measures, we found that only doing one is not enough to lower our risk of cancer. The study, which looked at more than 300,000 people, found that:
- People not meeting World Health Organization (WHO) guidelines on waist circumference are at 11% greater risk, even if they are physically active.
- People not meeting WHO guidelines for physical exercise are at 4% greater risk, even if “abdominally lean” (ie they have a smaller waist).
- Achieving neither means a 15% greater risk.
The study – WHO guidelines on waist circumference and physical activity and their joint association with cancer risk (Lead researcher: Prof Michael Leitzmann, University of Regensburg) – was published in the British Journal of Sports Medicine.
Prof Michael Leitzman
We're excited about the insights we’ve uncovered regarding the interplay between waist circumference and physical activity in reducing cancer risk. Our findings highlight the value of addressing multiple factors together, showing that both maintaining a recommended waist size and being physically active are critical for cancer prevention. This research reinforces the importance of practical, achievable changes that can have a meaningful impact on health over time.
Dr Helen Croker
This is the first study to examine the independent and combined impact of waist circumference and physical activity levels. The findings underscore the importance of a holistic approach instead of focusing on a single factor to reduce cancer risk. Maintaining a healthy weight and, in particular, having a waist circumference within the recommended level and being physically active, along with eating a healthy diet, are all crucial steps to reduce cancer risk. People can start by making small, sustainable changes like incorporating regular movement into daily routines or choosing healthier food options.
World Cancer Research Fund has been at the forefront of cancer prevention in the UK and globally for decades. We developed Activ8, a free 8-week programme to encourage people to move more, eat well and reduce their cancer risk. Every step is backed by science and brings our Cancer Prevention Recommendations to life.
At World Cancer Research Fund, our mission is to live in a world where no one dies from a preventable cancer, so of course they’re all designed to help you live a healthier, happier cancer free life!
25 things for 2025
1. Drink more water!
The human body comprises around 60% water, so drinking enough water will help improve your physical performance and increase your energy levels.
2. Eat more beans, legumes and pulses
They’re a great source of protein, iron and fibre, they’re much cheaper than meat and good for the climate.
3. Move more!
Being physically active is important to live a healthy life and it’s one of our Cancer Prevention Recommendations.
There’s also strong evidence that being active protects against cancers of the colon, breast and endometrium.
4. Eat more fibre
We should consume at least 30g of fibre a day. Eating a healthy balanced diet that contains plenty of fibre-rich food helps to support your general health and it helps to reduce your risk of bowel cancer.
5. Drink less alcohol
We have strong evidence to show consuming alcoholic drinks is a cause of 7 types of cancer and that there is no “safe” level of alcohol. Why not try a new mocktail recipe instead?
6. Eat more fruit
Fruit is a vital part of a healthy and balanced diet. It contains a variety of important vitamins, minerals and natural chemicals that our body needs.
7. Check your body regularly
Get into the habit of performing regular self-checks at home. As soon as you see or experience something new or something unusual, see a doctor. Even if it’s nothing, getting checked earlier is always better.
8. Eat more vegetables
Just like fruit (No6), it’s important to eat a range of vegetables. We have some evidence that eating non-starchy vegetables helps protects against some cancers of the mouth and throat.
9. Drink fewer fizzy or sugar-sweetened drinks
There’s strong evidence that regularly having sugar-sweetened drinks lead to weight gain over time, which can increase the risk of 13 types of cancer.
Stick to water or other unsweetened drinks, such as tea and coffee.
10. Eat less processed meat
There is strong evidence that consuming processed meat is a cause of bowel cancer. Ideally, you should cut back on all the bacon, sausages, pork pies and ham that you eat.
Research in 2023 showed that 8,500 bowel cancer deaths per year could be prevented if people stop eating processed meat.
11. Eat less red meat
Just like with processed meat, there’s evidence that too much red meat increases your risk of bowel cancer. But we don’t suggest you completely cut out red meat – it’s a good source of nutrients such as protein, iron, zinc and vitamin B12 so can form part of a healthy, balanced diet.
Our Recommendation is to eat no more than 3 servings of red meat a week. Opt for white meat and fish instead, or go meat-free.
12. Get better sleep
Sleep is vital for a healthy life, so whether it’s ditching screens before bed or establishing a routine, better sleep will have many benefits.
13. Opt for more wholegrains
Wholegrains are the seeds of cereal plants, such as wheat, barley, quinoa, oats, rye, maize (corn) and rice.
There’s evidence that they can decrease the risk of bowel cancer, as well as being a rich source of copper, zinc and dietary fibre.

15. Eat less fast food
There’s strong evidence that diets containing high amounts of “fast food” and processed foods high in fat, starches and sugars are a cause of weight gain, overweight and obesity, which has been linked to cancers.
A study in 2023 linked ultra-processed food to an increased risk of mouth and throat cancers.
16. Wear SPF and protect yourself from the sun
Each year, around 332,000 people are diagnosed with skin cancer globally, but a high-factor suncream, the right clothing and avoiding the sun between 11am–3pm can help decrease your risk.
17. Try a new recipe
Not only is it fun to cook new dishes, but it also introduces you to new flavours and can get you out of a rut of always cooking the same thing.
We have more than 350 healthy recipes to try – many of which are budget friendly, so you don’t have to break the bank.
18. Eat more protein
Protein is important for us maintaining our health and plays a role in maintaining your muscles, repairing any injuries, keeping your weight down (it keeps you fuller for longer), and it provides energy.
You don’t even need to eat lots of red meat to keep your levels up – nuts, seeds, eggs, wholegrains and pulses are all good sources of protein.
19. Get outside more
Keeping active is important and taking a break from screens and connecting with nature is good for both our mental and physical health.
Plus, spending 15 minutes a day in the sunshine helps restore the body’s vitamin D levels.
20. Ditch the sunbeds
If you want to get a tan, faking it is much safer.
21. Walk an extra 10 minutes a day
Get off the bus/train a stop early, or leave the car at home and walk to the shops. Small things add up quickly and soon you’ll prefer two legs over four wheels.
22. Sign up to our monthly newsletter
Get regular updates on our cancer prevention work, the latest research, health tips, new recipes and much more…
23. Have a meat free day
Or, why not try Veganuary? We’ve already mentioned that limiting red and processed meat is important for cutting your cancer risk.
And a 2022 study showed that following a vegetarian diet could cut your risk of cancer by 14%, so why not explore meat-free recipes.
24. Try a new sport or activity
If you’re in a slump or feeling generally demotivated, why not try something new? And, if sport isn’t your thing, gardening or yoga could get you moving more.
Alternatively, why not join a local group, such as a choir or a craft meet-up. Not only will you be learning something new, but you become part of a community, which provides multiple health benefits.
25. Change one thing
If this list has made you feel overwhelmed, don’t feel as you have to do them all. Start by picking just one thing to do differently and then build up from there. Before you know it, you’ll be thriving!

Science and football – while they may not seem like they have much in common, the disciplines meet in the person of Dr Frankie Brown. Frankie is an immunologist and former member of Scotland’s women’s team who has represented her country 96 times on the international stage.
Our funding helped Frankie realise her other dream of researching ways exercise can benefit those living with and beyond cancer.
Helping people with blood cancer

Frankie Brown with her Scotland team-mates
Under Dr Campbell from the University of Bath, Frankie worked in a team on a project funded by us investigating the effects of exercise on the health of patients with chronic lymphocytic leukaemia, a form of blood cancer that affects around 4,000 new people every year in the UK.
The team evaluated the safety and feasibility of a progressive exercise programme for these patients – many who were over 60. Essentially, they tested a “recipe for how to run a big study” more effectively, and even adapted it to continue successfully during the COVID pandemic.
She was inspired by her own background as a professional footballer, as well as her personal experience with cancer:
“When I was finishing up my PhD, my mum died of breast cancer. That was a real trigger moment for me to look more into oncology. I just couldn’t get my head around it – she had been so healthy. I would wonder, what’s going on here?
“I already knew a lot about health and monitoring my body for football. I started playing football very young, playing with my little brother, and I haven’t stopped since. I was in the Scotland under 17s, then the under 19s, and got into the full squad when I was 21 and was there for 10 years.
“Having spent my whole life in a high-performance environment, with everything being tested and monitored, I became more aware of how my body reacts to even very small shifts in circumstances and situations. It wasn’t hard for me to see how those tiny changes that are so important to athletes can be important for everybody.”
This inspired Frankie to become a researcher, where she found herself on the team led by Dr Campbell and funded by us. There were, however, some setbacks along the way – the biggest being the COVID-19 pandemic. Thanks to the flexibility of our funding programme, Frankie says she and the rest of the team were able to pivot from designing the programme to be in-person, to buying the participants exercise bikes and running a group session over Zoom.
“We had to shift the whole design of the exercise sessions to be home-based and World Cancer Research Fund allowed us to deliver exercise bikes to the participants’ homes. Without that, the trial would have fallen apart.“
‘The more muscle mass you have as you get older, the more independent you will be’
The data showed a 2% increase in lean mass in the exercise group compared with a 0.4% decrease in the control group. This is a significant benefit, as Frankie explains: “The data we have now and the study we’ve done shows that any gain a patient can make with their performance can make a huge difference to their own wellbeing.
“An increase in lean mass – in other words, in muscle mass – in these patients is a huge thing, especially in people over 60. The more muscle mass you have as you get older the more independent you will be. One of our participants lived up some stairs, and whenever I think about the study, I think about them and hope that my work has made it easier for them to get the shopping up and down to their home.”
These results have informed the design of a larger study where Frankie and her team will assess the tumour-suppressing effects and mechanisms of exercise in humans.
Frankie is very vocal about the impact of our support on her work: “In my experience, World Cancer Research Fund has been incredibly supportive of me as a young academic. They’ve provided amazing flexibility at a very uncertain time. I wouldn’t have been able to achieve any of this without you.”
