What are polyps? They are abnormal tissue growths that usually appear as small, flat bumps or mini mushroom-type stalks. Most are less than half an inch wide. There are two types: non-neoplastic and neoplastic polyps. Non-neoplastic polyps consist of hyperplastic polyps, inflammatory polyps, and hamartomatous polyps. These types usually do not become cancerous. Neoplastic polyps, adenomas and serrated, are often the larger of the varieties and have a higher the risk of cancer.
The colon is the most common place polyps develop, though they may also grow in the ear canal, nose, throat, or stomach. The cervix and uterus are also prone to polyps.
