title: Avoidable nondietary risk factors for cancer.
abstract: Smoking cessation has the greatest potential for reducing cancer mortality. Moderate physical activity may prevent colon cancer by modifying bowel peristalsis patterns and may prevent breast cancer by modifying ovulatory frequency. Radiation therapy and the use of certain drugs may increase the risk of some cancers. Liver cancer may be the most preventable major cancer.
