Rectal cancer is a type of cancer that occurs in the rectum, the last part of the large intestine. It typically develops from polyps, which are small growths on the lining of the rectum. Symptoms may include changes in bowel habits, blood in the stool, and abdominal discomfort. Early detection is crucial for effective treatment. Risk factors for rectal cancer include age, family history, and certain lifestyle choices, such as a diet high in red or processed meats. Screening methods, such as colonoscopy, can help identify precancerous polyps and early-stage cancer, improving the chances of successful treatment and recovery.
