Diet and Physical Activity in Cancer Prevention

Abstract

KEY POINTS Cancer confers a major disease burden worldwide, especially in affluent societies. Cancer incidence and mortality between low risk and high risk countries differs several-fold. These differences are ascribed such environmental factors as lifelong dietary behaviors, physical inactivity, weight gain, alcohol consumption, and the use of tobacco. Through a healthy diet, optimal levels of physical activity and by maintaining normal body weight, a large proportion of cancers may be prevented.
