Colorectal Cancer in Men

Colorectal cancer is a type of cancer that starts in the colon or rectum, which are part of the digestive system. Colorectal cancer is the third most common type of cancer in men after prostate and lung cancer, and it is the second most common cause of cancer death in men in the United States.

Risk factors for colorectal cancer in men include age, a family history of colorectal cancer, a history of inflammatory bowel disease, a personal history of polyps or colorectal cancer, a diet high in red or processed meat, physical inactivity, obesity, smoking, and heavy alcohol use.

To reduce the risk of colorectal cancer, men should maintain a healthy lifestyle that includes regular physical activity, a diet that is high in fruits, vegetables, and whole grains, and low in red and processed meats, and avoiding smoking and excessive alcohol consumption.

Men who are at average risk for colorectal cancer should start getting screened at age 45, while those at higher risk may need to start screening earlier or more frequently. Screening tests include colonoscopy, flexible sigmoidoscopy, stool tests, and virtual colonoscopy.
