Blueprint to beat cancer launched today by World Cancer Research Fund (WCRF)

May 23, 2018

Overweight and obesity increase cancer risk. A new report published today by World Cancer Research Fund (WCRF) shows that overweight or obesity is a cause of at least 12 cancers**, five more than WCRF findings a decade ago. [**Liver, ovary, prostate (advanced), stomach (cardia), mouth and throat (mouth, pharynx and larynx) join bowel (colorectum), breast (post-menopause), gallbladder, kidney, oesophagus (oesophageal adenocarcinoma), pancreas and womb (endometrium).]

Other key findings include:Lifestyles featuring little exercise and lots of fast and processed food are fuelling overweight and obesity, resulting in dramatic increases in cancer rates worldwide, according to the new report from WCRF, leading authority on the links between diet, weight, physical activity and cancer prevention and survival. Around one in six deaths annually worldwide are due to cancer. As more countries adopt 'Western' lifestyles, the number of new cases of cancer is expected to rise by 58% to 24 million globally by 2035.

The new report - Diet, Nutrition, Physical Activity and Cancer: a Global Perspective - is the result of an ongoing review of decades of evidence by world-renowned, independent experts from across the globe. It provides strengthened evidence for a comprehensive package of behaviours that, when followed together, represent the most reliable blueprint available for living healthily to reduce cancer risk: WCRF announces today its ten, updated Cancer Prevention Recommendations.

With more than 3.7 million new cases and 1.9 million deaths each year, cancer represents the second most important cause of death and morbidity in Europe. On a global scale, cancer accounted for 8.2 million deaths (around 13% of the total) in 2012. Europe comprises only one eighth of the total world population but has around one quarter of the global total of cancer cases with some 3.7 million new patients per year. (See 'Notes to editors' for reference.) Further, as WCRF's latest report indicates, the quality of diet and levels of activity of most people living in wealthy societies do not encourage healthy ageing, so further impact on cancer rates is anticipated as populations age worldwide.

Dr Giota Mitrou, WCRF's Director of Research Funding and External Relations, today (24 May) chairs a session presenting the findings of Diet, Nutrition, Physical Activity and Cancer: a Global Perspective at ECO 2018, the 25th European Congress on Obesity, in Vienna. NB: there will be an embargoed press conference at ECO 2018 on 23 May.

Dr Mitrou said: "Our research shows it's unlikely that specific foods or nutrients are important single factors in causing or protecting against cancer. Rather, different patterns of diet and physical activity throughout life combine to make you more or less susceptible to cancer. Our Cancer Prevention Recommendations work together as a blueprint to beat cancer that people can trust, because they are based on evidence that has now proved consistent for decades."

WCRF is committed to giving people the most up-to-date and authoritative information about cancer prevention and survival, enabling them to make healthy lifestyle choices in their daily lives to reduce their cancer risk. So WCRF is also today launching a brand new, online Cancer Health Check tool. By answering some simple questions about their lifestyle, people can see which areas they are doing well in, and which areas they could make changes in, to reduce their cancer risk.However, cancer prevention depends not only on individual choices but also on governments creating an environment that encourages lifelong healthy eating and a physically active lifestyle. WCRF today calls on governments to prioritise cancer prevention through the development and implementation of effective policies to address the rising burden of cancer in the UK and worldwide. WCRF representatives are currently at the 71st World Health Assembly in Geneva (1-26 May), reinforcing this message.

Meanwhile, leading researchers, scientists, policymakers and other opinion-formers in the field will gather at the Royal Society in central London on 24 May to hear key findings from the new WCRF report, and its latest Cancer Prevention Recommendations. They will debate their implications for future cancer research directions, how to translate them into public health and policy action, and the implications for cancer survivorship.

Background to the new report: WCRF's Continuous Update Project (CUP) brings together an independent panel of scientists to carry out regular, systematic analyses of research into the links between diet, weight, physical activity and cancer prevention and survival, resulting in landmark WCRF cancer prevention reports in 1997 and 2007, and now the publication of Diet, Nutrition, Physical Activity and Cancer: a Global Perspective. For this latest report, the panel reviewed studies on 17 cancers, comprising 51 million people of whom 3.5 million were diagnosed with cancer. Studies evaluating adherence to WCRF's Cancer Prevention Recommendations from 2007 have confirmed the positive impact of following them (please see below for references).

The World Cancer Research Fund network comprises American Institute for Cancer Research, Wereld Kanker Onderzoek Fonds (Netherlands), World Cancer Research Fund Hong Kong, World Cancer Research Fund UK and World Cancer Research Fund International - the latter has held official relations status with the World Health Organization since 2016.
