New Evidence on Preventing Cancer Through Lifestyle

Global experts from the World Cancer Research Fund confirm that diet, physical activity and body weight are key modifiable factors in cancer risk. Their review of hundreds of studies shows that healthier eating, maintaining a healthy weight and staying active are consistently linked with lower risk for many common cancers. Diets rich in whole grains, vegetables, fruits and pulses are associated with reduced cancer risk, while high intake of red and processed meats, sugary drinks and ultra processed foods is linked to higher risk. The findings highlight that overall dietary patterns matter more than single food choices. Regular physical activity lowers the risk of cancers such as breast and colon cancer. Movement helps regulate hormones, reduce inflammation and support healthy weight, reinforcing that even everyday activity like brisk walking contributes to prevention.
