Regular physical activity significantly reduces the risk of developing colon cancer in both males and females, with occupational and recreational exercise showing protective effects.

Engage in regular physical activity, whether through your job or leisure time, to lower your risk of colon cancer. This benefit exists independently of weight loss and works for both men and women. While it doesn't appear to protect against rectal cancer, the evidence for colon cancer protection is strong.
