Colonic polyps are a small clump of cells that forms on the lining of the colon. Most colon polyps are harmless. But over time, some colon polyps can develop into colon cancer, which may be fatal when found in its later stages.
Examples of colonic polyps are:
- Hamartomatous polyps: juvenile polyps. Peutz-Jeghers syndrome
- Hyperplastic polyps
- Inflammatory polyps
- Neoplastic polyps
- Adenomatous polyps
