* If you already smoke, quit for good as soon as you can. Smoking (including cigarettes, pipes, cigars, and chewing tobacco) is linked to cancers of the lung, throat, pancreas, kidney, bladder, cervix, prostate, colon, and rectum.
* If you're overweight, lose weight. If you're already at a healthy weight, maintain it. Being overweight increases risk for cancers of the colon, rectum, uterus, and breast.
* Being physically active lowers risk of colon cancer and may lower the risk of breast cancer.
