A colon polyp is 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 is often fatal when found in its later stages. There are two main categories of polyps, non-neoplastic and neoplastic. Non-neoplastic polyps include hyperplastic polyps, inflammatory polyps and hamartomatous polyps. These types of polyps typically do not become cancerous.
An intestinal polyp is any mass of tissue that arises from the bowel wall and protrudes into the lumen. Most are asymptomatic except for minor bleeding, which is usually occult. The main concern is malignant transformation; most colon cancers arise in a previously benign adenomatous polyp. Diagnosis is by endoscopy.

Polyps are abnormal growths rising from the lining of the large intestine colon or rectum. The rectum is the last 12 inches of the large intestine. Polyps may be flat sessile or develop on a stalk like broccoli. This is called a pedunculated polyp. Polyps are one of the most common conditions affecting the large intestine occurring in percent of the adult population.
