Eating a healthier diet, increasing physical exercise, reducing alcohol consumption, and stopping smoking are all modifiable lifestyle choices that could help prevent up to two thirds of cancer suggests new research. Organizations such as the American Cancer Society (ACS) and the World Cancer Research Fund/American Institute for Cancer Research (WCRF/AICR) have set recommendations on diet and physical activity as part of their cancer prevention strategy. New research analyzed 12 prospective cohort studies published within the last ten years to look at the association between following these guidelines and cancer incidence and mortality.
