We’re delighted to announce £4m of funding to help more people prevent and survive cancer, in the latest round of grants awarded by World Cancer Research Fund International.

Dr Charlotte Le Cornet is looking at how persistent organic pollutants (POPs) – pollutants that are produced or released during industrial or agricultural processes – affect a woman’s risk of breast and womb cancers. Dr Le Cornet is using data in the European Investigation into Cancer and Nutrition cohort.

Prof Reginald Adjetey Annan is our first ever principal investigator who is from, based in, and researching in Africa. Prof Annan, at Ghana’s Kwame Nkrumah University of Science and Technology, will look at breast cancer among sub-Saharan women. Prof Annan took part in a grant writing course for researchers in Africa organised by Cancer and Nutrition in Africa as an initiative of the International Collaboration on Nutrition in relation to Cancer, which we helped fund in 2023 and 2024.

The grant writing course for researchers in lower- and middle-income countries (LMICs) aims to produce successful grant applications that address unmet needs and focus on understudied populations within these countries. Our investment in such initiatives underscores our commitment to fostering research excellence in LMICs and advancing global health equity.

We fund 2 types of projects: our Regular Grant Programme for established senior scientists, and our INSPIRE Research Challenge for scientists starting out on a career in cancer research.

Our grants are managed by World Cancer Research Fund International on behalf of our network funders: World Cancer Research Fund in the UK, and Wereld Kanker Onderzoek Fonds in the Netherlands. Our network partner, American Institute for Cancer Research, runs a separate grant call for researchers based in the Americas.

A new study funded by World Cancer Research Fund has found that activity throughout the day, with peaks in the morning and late afternoon, correlated with an 11% reduced risk of developing colorectal (also known as bowel) cancer, compared with other patterns of exercise studied.

This study used accelerometer data (which measures movement) to analyse daily activity. It used a statistical method that examines all of the data and finds common patterns, and how those patterns might be related to the risk of colorectal cancer.

Researchers from Regensburg University utilised data from the UK Biobank, which had contacted 86,252 randomly selected individuals (56% of them women), asking them to wear accelerometers to track their movement over 1 week and following them for 5 years to monitor the development of colorectal cancer. When studying the data, researchers identified a 2-peak pattern of daily physical activity associated with reduced colorectal cancer risk.

The researchers identified 4 different patterns of physical activity throughout the day:

  1. Continuous day-long activity
  2. Activity later in the day
  3. Early and late-day activity
  4. Activity in the middle of the day and during the night

The 3rd pattern, where people were active both in the early and late parts of the day, was associated with an 11% lower risk of colorectal cancer, compared with 6% for day-long activity and no change for middle of the day and the night. Data from activity later in the day only was inconclusive. These findings held true even when considering factors such as smoking, shift work and other variables that could affect a person’s cancer risk.

Impact on sedentary lifestyles

In addition, the researchers found that a day-long activity pattern most effectively reduced colorectal cancer risk among individuals who were more sedentary. This may be because the effect of physical activity becomes more obvious when contrasted with a previously more inactive lifestyle, meaning that those who are fit and healthy are already at a reduced level of cancer risk. These findings show how beneficial physical activity can be, especially in those who are more sedentary.

Dr Helen Croker, Assistant Director of Research and Policy at World Cancer Research Fund, said:

“Being physically active is one of our Cancer Prevention Recommendations, and we know that this cuts cancer risk. These intriguing new findings offer potential for developing more specific recommendations, including patterns and timing of physical activity, for reducing cancer risk. This shows the vital importance of World Cancer Research Fund continuing to support research that expands our knowledge to inform cancer prevention going forwards.”

Prof Michael Leitzmann, Chair of the Department of Epidemiology and Preventive Medicine at the University of Regensburg, Germany, who was the lead investigator in the study, said:

“Our study highlights that not only is physical activity important for reducing colorectal cancer risk, but the timing of peak activity throughout the day could play a crucial role. By identifying specific times – early morning and late day – when physical activity is most beneficial, our findings open new avenues for targeted prevention strategies. If confirmed by future research, this could provide a simple yet impactful way for individuals to further reduce their cancer risk through the timing of their exercise.”

Adulthood Dietary and Lifestyle Patterns and the Risk of Breast Cancer: Global Cancer Update Programme (CUP Global) systematic literature review

  • Notes

    The review was done by a team led by Dr Dora Romaguera from the Health Research Institute of the Balearic Islands (IdISBa) and  Biomedical Research Networking Centre – Physiopathology of Obesity and Nutrition (CIBEROBN).

    The CUP Global research team at Imperial College London, led by Dr Doris Chan and Dr Kostas Tsilidis, supported this work.

  • New guidance developed with experts including patients and service users
  • Our Cancer Prevention Recommendations are beneficial after a cancer diagnosis
  • Comprehensive review of evidence and recommendations for future research directions

Two new in-depth scientific reports, launched at the World Cancer Congress in Geneva, bring together a full synthesis of the current evidence on diet, nutrition, physical activity and body weight from World Cancer Research Fund International’s Global Cancer Update Programme (CUP Global) on people living with and beyond breast and colorectal cancers.

For the first time, they present guidance for people living with and beyond breast and colorectal cancers, caregivers and health professionals. The reports also discuss the limitations of the existing research and make recommendations for future research to strengthen the evidence base.

Relevant and accessible

The CUP Global research team at Imperial College London conducted 7 systematic reviews, together assessing many thousands of recent research papers, studies and databases. World Cancer Research Fund convened expert panels, including oncologists and researchers, as well as patients and people with lived experience of cancer, to ensure the guidance is relevant and accessible.

Prof Andrew Renehan, Deputy Chair of the CUP Global Expert Committee on Cancer Survivorship, said:

These reports are the culmination of over 2 years of detailed work by World Cancer Research Fund International and the CUP Global partnership. They are a substantial and significant body of work and represent the best synthesis of our knowledge to date. As well as providing guidance for oncology health professionals and people living with and beyond cancer, they offer a clear direction for researchers seeking to advance the field.

Lynette Hill, Public Representative on the CUP Global panel, said:

Our challenge was to translate the complex findings from so many scientific papers into simple messages for people living with and beyond cancer. This will help health professionals to answer questions and inform their patients about the role of diet, physical activity and body weight, and the importance of these to their future health.

The reports show how nutrition, physical activity and body weight affect survival and recurrence. For people living with and beyond breast cancer, there is strong evidence that a physically active lifestyle improves health-related quality of life and that a diet high in fibre may improve health outcomes. For colorectal cancer, the evidence suggests that physically active lifestyles and a diet rich in wholegrain foods, and avoiding sugary drinks, may improve health outcomes and overall survival.

Key evidence in the reports was recently published in a series of linked papers in the International Journal of Cancer, published by the Union for International Cancer Control (UICC),

Dr Sonali Johnson, Head of Knowledge, Advocacy and Policy at the UICC said:

The guidance provided in these reports is about giving people living with cancer the tools they need to take control of their health. By focusing on practical changes such improving diet, staying active and managing weight, we can help reduce the risk of cancer coming back and improve the quality of life for so many, bringing us closer to a world where fewer lives are lost to cancer, and more people can live healthier, longer lives after diagnosis.

World Cancer Research Fund’s CUP Global is the world’s largest source of scientific research on cancer prevention and survivorship through diet, nutrition, physical activity and body weight. It is funded in partnership with American Institute for Cancer Research, World Cancer Research Fund in the UK and Wereld Kanker Onderzoek Fonds in the Netherlands.

Dr Helen Croker, World Cancer Research Fund International’s Assistant Director of Research and Policy, and Head of the CUP Global Secretariat, said:

As an evidence-based organisation, we have used the best available evidence to develop this process and produce practical guidance on diet, physical activity and body weight for people living with and beyond cancer. We hope this guidance will help support people to live longer, healthier lives.

By highlighting gaps in the evidence base, the reports show where further, high-quality research is needed. These include well-designed clinical trials and prospective cohort studies, as well as understanding the biological mechanisms involved. We hope this will be a springboard for further progress.

Summary guidance in the reports

  • Suggests that people living with and beyond breast and colorectal cancers consider increasing their physical activity, under the supervision of health care professionals.
  • Suggests that people living with and beyond breast and colorectal cancers consider following as many of WCRF/AICR’s Cancer Prevention Recommendations as they are able.
  • People diagnosed with breast cancer should consider:
  1. increasing their dietary fibre intake.
  2. avoiding gaining weight during and after treatment (if not underweight).
  • People diagnosed with colorectal cancer should consider increasing their dietary intake of wholegrain foods, and reducing their sugary drink intake.

Much of the research in these reports build on the 2014 (updated 2018) report: Diet, nutrition, physical activity and breast cancer survivors, which was published as part of the WCRF/AICR Third Expert Report on the links between lifestyle/modifiable behaviours and cancer. At that time, research on cancer survival was limited, but there was enough evidence to conclude that people living with and beyond cancer should follow our Cancer Prevention Recommendations if they can.

Read the executive summary:

2 May 2024

Our latest findings have been published in the International Journal of Cancer (IJC), presenting research from our Global Cancer Update Programme (CUP Global) – a comprehensive review of the available literature and evidence.

The CUP Global research team at Imperial College London, supported by World Cancer Research Fund International, conducted comprehensive systematic literature reviews and meta-analyses to evaluate the evidence on body fatness, physical activity, sedentary behaviour and diet with predicted outcomes after a colorectal cancer diagnosis.

Overall, the evidence suggested a physically active lifestyle, a diet rich in plant-based foods, wholegrain foods, and coffee, but avoiding sugary drinks, potentially improve outcomes and overall survival.

The quality of the evidence was independently interpreted and graded by the CUP Global Expert Committee on Cancer Survivorship and Expert Panel. The Panel graded the quality of the strongest evidence as “limited-suggestive”, however, the rest was graded “limited-no conclusion”.

Only very few relevant randomised control trials (RCTs) with relevant exposures were identified. Many of the studies available for review were observational, looking at a relatively small sample over a limited time. The authors and Panel flagged the high risk of possible biases including confounding elements, inaccurate exposure measurements, and selection bias (inclusion only of patients with some accumulated survival time).

The authors and Panel are calling for better-designed intervention trials and large, well-designed observational studies with more accurate and repeated exposure and confounder information to strengthen this evidence-base. This will allow them to develop improved recommendations for colorectal cancer survivors.

Dr Helen Croker, Assistant Director of Research and Policy at World Cancer Research Fund International, said:

This comprehensive and rigorous review of the current state of evidence offers useful guidance on some of the diet and lifestyle factors that could improve cancer survival, and potentially help people living with and beyond cancer enjoy longer, healthier lives.

At the same time, it shows a clear need for more well-designed intervention and cohort studies to support the development of robust recommendations for colorectal cancer patients and health professionals. As we are seeing an increase of people diagnosed with colorectal cancer at younger ages, it is more important than ever that health advice is based on high-quality research.

Dr Doris Chan, Senior Research Fellow in Nutrition at Imperial College London, and Dr Kostas Tsilidis, Reader in Cancer Epidemiology and Prevention at Imperial College London – both CUP Global lead researchers – said:

We are delighted that our findings have been evaluated by the Expert Panel and are published today in IJC. We analysed several hundred studies, and although most had limitations and potential biases, we are confident that it represents the best and most up-to-date body of evidence that can assist people living with or beyond cancer in making evidence-based decisions on lifestyle changes that can improve their well-being. We are now moving forward with the next phase of CUP Global, including employing AI-enhanced tools to assist us in our examination of cancer risk factors and prevention strategies.

Prof Rudolf Kaaks, Chair in Cancer Epidemiology at the German Cancer Research Center, is the author of the IJC editorial that accompanies the papers. He wrote:

Through its international Global Cancer Update Programme WCRF takes up a central role in organising international expert reviews to summarise the impact of diet, physical activity and excess body weight which provides reliable recommendations on body weight, physical activity and diet in relation to cancer risk.

WCRF and the Imperial College London research team in charge of the CUP Global evaluations are to be commended for their continuing efforts of summarising findings from nutritional epidemiology studies setting highest possible standards for scientific evaluation.

Prof Kaaks’ editorial also refers to a set of linked papers on breast cancer survival, published by the CUP Global team in 2023.

International Journal of Cancer is a bi-weekly peer-reviewed medical journal, and the official journal of the Union for International Cancer Control (UICC).

Dr Sonali Johnson, Head of Knowledge, Advocacy and Policy at the Union for International Cancer Control, said:

The Union for International Cancer Control commends the World Cancer Research Fund for its rigorous scientific inquiry, further advancing our understanding of cancer survivorship, as well as improving outcomes and the quality of life of people who have had cancer. This study also underscores the importance of robust research and data in informing protocols, policies and national cancer strategies.

World Cancer Research Fund International has convened a new Science Executive Committee to steer its scientific programmes, including the flagship Global Cancer Update Programme.

Prof Elio Riboli, chair in Cancer Epidemiology and Prevention at the School of Public Health, Imperial College London, will chair the Committee in his new role as World Cancer Research Fund’s International Medical and Scientific Adviser. Dr Panagiota Mitrou, Director of Research, Policy and Innovation at World Cancer Research Fund International, will co-chair the Committee.

The Science Executive Committee will advise on progress, new research directions, dissemination of outputs, policy implications, and opportunities for leverage with stakeholders and partnerships.

‘We must face the reality’

At the inaugural meeting, which took place in London last month, Prof Riboli said:

“I am delighted to be supporting this vital work at a very exciting time. Our understanding of the links between nutrition, weight, physical activity and cancer continues to increase, and there are great opportunities to influence both the direction of research and public health policy.

“At the same time, we must face the reality that in many countries, the trend is for increasing consumption of processed and red meat, sugary foods and drinks, and other unhealthy food. These dietary habits, combined with low levels of physical activity, contribute to the increase in overweight and obesity, and in the incidence of many common chronic diseases around the world. We need to understand and focus on system-level interventions that improve the health of individuals and populations – and this is a huge challenge.”

Dr Mitrou said:

“Prof Riboli is one of the world’s eminent leaders in cancer epidemiology and prevention. We’re delighted that he’s joining World Cancer Research Fund as our Medical and Scientific Adviser. His input will be vital to build on the success of our funded research through our grant programmes and our global expert reports on diet, nutrition and physical activity in relation to cancer prevention and survival. Our ultimate aim is to strengthen our science strategy, explore new directions and translate evidence into policy.”

World Cancer Research Fund International is a leading authority on the links between diet, nutrition, weight, physical activity and cancer. It is in official relations with the World Health Organization (WHO) and works with partners globally to promote policies that prevent cancer and other non-communicable diseases.

Rachael Gormley, CEO of World Cancer Research Fund International, said:

Our vision is a world where no one develops a preventable cancer, and people living with and beyond cancer are enabled to make informed choices and enjoy longer, healthier lives. We can only realise this in partnership with others, taking leadership in some areas and supporting in others. With his experience and eminence in the field, Prof Riboli is a tremendous addition to our team.

About Prof Riboli

Prof Riboli has made an exceptional impact on the fields of epidemiology, cancer prevention and the fight against chronic illness. Before coming to Imperial, he worked at the International Agency for Research on Cancer, the specialised cancer agency of the WHO, where he initiated groundbreaking research on the role of diet, nutrition and metabolic health in cancer causation and prevention.

He designed and led the establishment of the largest international population cohort studies on nutrition and cancer – the European Prospective Investigation into Cancer and Nutrition (EPIC) – which recruited more than half a million participants, with rich phenotyping data and blood samples stored in the first dedicated large-scale population biobank.

At Imperial, he has continued to lead research on modifiable cancer risk factors, including metabolic syndrome components and inflammation.

In recognition of his achievements, Prof Riboli was elected an Honorary Fellow of the Faculty of Public Health of the Royal College of Physicians and a Fellow of the Academy of Medical Sciences.

Prof Ellen Kampman discusses her research

People who have had bowel cancer who drink more than 4 cups of coffee per day have a lower risk of the cancer recurring than those who have 2 or fewer cups.

They also have a lower risk of death following their diagnosis, according to new research recently published in the International Journal of Cancer.

The study found that participants who drank more than 4 cups of coffee had a 32% lower risk of cancer recurrence than participants who drank less than 2 cups per day in terms of relative risk. In addition, the risk of dying was lower among coffee drinkers, and 3–5 cups of coffee per day seem sufficient to improve survival.

The observational study, funded by World Cancer Research Fund*, analysed a cohort of 1,700 people in the Netherlands of median age 66, who were diagnosed and treated for colorectal cancer, commonly known as bowel cancer, since August 2010.

Of 540 patients who reported drinking more than 4 cups of coffee per day, 73 (13.5%) experienced cancer recurrence. This is significantly lower than those who drank fewer than 2 cups per day, (89 out of 499 or 17.8%). In addition, relatively fewer of those who reported drinking more coffee have died since their diagnosis, with the lowest all-cause mortality at around 4 cups per day.

Previous evidence from World Cancer Research Fund shows that coffee can help protect against several cancers including liver and womb cancers. This is despite public perception that coffee may not be healthy. For example, polling conducted by YouGov on behalf of World Cancer Research Fund has shown that 12% of all UK adults mistakenly believe that drinking coffee increases cancer risk**.

People who have had a cancer diagnosis or treatment are advised to follow World Cancer Research Fund’s evidence-based Cancer Prevention Recommendations, the conclusions of an independent panel of experts.

Notes to Editors

About the research

This study used data from a prospective cohort of colorectal cancer patients, the “Colorectal cancer: Longitudinal, Observational study on Nutritional and lifestyle factors that influence colorectal tumor recurrence, survival and quality of life” (COLON) study.

The study found that of 540 patients who reported drinking more than 4 cups of coffee per day, 73 (13.5%) experienced cancer recurrence. This is lower than for those who drank 2–4 cups per day (93 out of 664 or 14%) and significantly lower than those who drank less than 2 cups per day, (89 out of 499 or 17.8%).

In addition, relatively fewer of those who reported drinking more coffee have died since their diagnosis, with the lowest all-cause mortality at around 4 cups per day. Of the 1,700 people, approximately 300 (18%) have died of all causes.

*The study was funded by Wereld Kanker Onderzoek Fonds in the Netherlands as part of World Cancer Research Fund International’s grant programme.

The study did not assess different types of coffee; in their subsequent analysis of metabolomics, the authors intend having more detailed insights into coffee type, the metabolites responsible, and potential mechanisms.

The study focuses on coffee consumption and does not include tea consumption. The association the researchers observed remained the same after accounting for tea consumption in the data analysis.

Preventing Cancer. Saving Lives

About YouGov Poll

**All figures, unless otherwise stated, are from YouGov Plc.  Total sample size was 2092 GB adults. Fieldwork was undertaken between 28–29 June 2023.  The survey was carried out online. The figures have been weighted and are representative of all GB adults (aged 18+).

World Cancer Research Fund part-funded the study authored by the International Agency for Research on Cancer (IARC) which has found connections between early-onset bowel (also known as colorectal) cancer and various genetic and socio-economic factors. They found strong links with body fat, alcohol consumption, and educational attainment.

This genome-wide association study, the first of its kind, looked at more than 70,000 people, including almost 6,200 people under 50 who had been diagnosed with bowel cancer. Rates of early-onset bowel cancer are on the increase in many parts of the world, but the reasons are not yet fully understood.

The researchers identified new genetic variants associated with the development of early-onset bowel cancer, as well as confirming known pathways involved in bowel cancer development.

The team used Mendelian randomisation, which is a statistical way of analysing genetic variation between people. It analyses risk factors both independently and together, to help disentangle the direction of causality.

World Cancer Research Fund is funding research into many aspects of bowel cancer, for both prevention and survival, including the associations highlighted in this study. We are funding another study by Dr Murphy on bowel cancer in younger adults, as we work towards a world where no one dies of a preventable cancer.
