DefinitionBy Mayo Clinic staff
A colon polyp is a small clump of cells that forms on the lining of the colon. Although most colon polyps are harmless, some become cancerous over time.
Anyone can develop colon polyps. But you're at higher risk if you're 50 or older, are overweight or a smoker, eat a high-fat, low-fiber diet, or have a personal or family history of colon polyps or colon cancer.
Usually colon polyps don't cause symptoms. That's why experts recommend regular screening. Colon polyps that are found in the early stages usually can be removed safely and completely. Screening helps prevent colon cancer, a common disease that's often fatal when it's found in its later stages.
