If you read or listen to the media it can be easy to get the impression that scientists are constantly changing their minds about what increases and reduces cancer risk.
This is because individual scientific studies that are often reported in the press as scientific fact are not big enough to base conclusions on. Sometimes scientists will find that chemicals or cells react in a certain way in one circumstance but that is no guarantee the same result would happen in different circumstances.
This is the one of the reasons why it is easy to get confused about the links between cancer and lifestyle, even though there is actually widespread agreement among scientists about how people can reduce their risk.
In 2007 we published a landmark report that looked at all the evidence on cancer prevention and made 10 Recommendations for Cancer Prevention. This information is being updated and analysed on a ongoing basis through our Continuous Update Project (CUP).
Following our Recommendations is a much better way of reducing your risk of cancer than making changes based on the latest newspaper headline. You can be confident that you are following the best advice on cancer prevention available anywhere in the world.
You could have a healthy lifestyle and still develop cancer, or you could have an unhealthy lifestyle and never be affected by it. But this does not change the fact that making healthy lifestyle choices can make a significant different in reducing your cancer risk, as well as the risk of other chronic diseases.
No. 5-10% of all cancers result from specifically inherited genes. It is now known that the risk of cancer is mainly affected by environmental factors, including smoking, weight, diet, physical activity and some industrial chemicals and pollutants.
This means there are roughly 90,000 preventable cases of cancer diagnosed in the UK every year – that’s enough people to fill Wembley Stadium.

It is never too early or too late to make the kind of healthy lifestyle choices that can reduce cancer risk. The scientific research is increasingly showing that our cancer risk is affected by what we do throughout the course of our whole lives.
For example, being breastfed probably reduces a child’s chance of being overweight, which increases cancer risk, and scientists even believe that what happens to the baby in the womb can affect its risk of cancers later in life.
This means it is never too early to start thinking about cancer prevention, which is why we fund a children’s education programme. Getting children into healthy habits as early as possible can make a positive difference to their risk of developing cancer later in life.
Similarly, it's never too late to make the kind of healthy lifestyle choices that can reduce cancer risk.
Scientists believe that making healthy lifestyle changes can make a positive impact no matter how old you are. The best advice for older people is to eat healthy foods, maintain a healthy weight and be physically active for both cancer prevention and also risk of heart disease.
World Cancer Research Fund’s (WCRF) mission is different from other cancer charities. Their activities are often very wide ranging and often include aspects of the treatment and care of cancer patients. WCRF focus is specifically on cancer prevention through diet, nutrition and lifestyle.
Each cancer charity plays an important role but we feel that this area of cancer prevention research has not received the financial support and attention it deserves. Considerable scientific evidence suggests an association exists between an individual’s diet and their risk of developing cancer and WCRF works to expand on that evidence and share it with individuals who can then change their lives.
Information regarding how we spend donations can be found in our Annual Review.
Over the years WCRF UK has funded millions of pounds of scientific research that has helped us better understand how people can make lifestyle choices to reduce their risk of cancer.
We also have health information programmes that interpret the latest scientific research and communicate this to the general public. Recent opinion polls show that there are increased levels of awareness about cancer risk factors.

WCRF UK funded research is administered by WCRF International, along with all other WCRF network funded research. Information about what research is taking place in the UK can be found in the funded research section of this site or you can find details of all current and past funded research on the WCRF International funded research page.
