Cancer Prevention Action Week (CPAW) 2026 was a real success and a positive first step in what will be a three-year campaign. This year was very much about raising awareness of the scale and seriousness of health misinformation, particularly around nutrition, supplements, cancer prevention and cancer. As the campaign develops, we will be moving increasingly towards action. 

Firstly, thank you to Alex Ruani, who worked with us to create the TRUST Test and supported the campaign through media, events and sharing the message with her networks. Thank you also to Dr Liz O’Riordan and Dr Philippa Kaye for their support throughout the development of the campaign, for acting as media spokespeople, appearing on radio and national TV, sharing across their networks and giving the campaign a platform at events. 

We are especially grateful to Sharron Moffatt for so bravely sharing her story and calling out the scale and impact of health misinformation, particularly how difficult it can be to navigate after a cancer diagnosis. 

We have already received some incredible feedback and will now test further to understand how it is perceived by the public, patients, and professionals. We would really value your feedback on it too, and would be grateful if you could take just 5 minutes to complete our survey.

During the week, we had more than 30 health professionals and experts backing the campaign, alongside organisations including the British Dietetic Association, the NIHR Cancer and Nutrition Collaboration, Patient Information Forum, International Agency for Research on Cancer (IARC), Our Future Health, Alcohol Change UK, Union for International Cancer Control (UICC), the Alcohol Health Alliance and the Obesity Health Alliance among many others. 

We were also able to secure significant public and media engagement, including national press and powerful stories from people living with and beyond cancer, as well as support from MPs across their own channels. On 22 June, we also attended a roundtable on misinformation in the UK Parliament organised by author Deborah Cohen, which was another important moment in building momentum around this issue. 

Cancer misinformation is an ongoing issue that we are taking very seriously. Together, we are stronger and together, we can help ensure people have access to information they can trust so that we can all live longer, healthier and happier lives free from the fear of cancer.
