Colon polyps are small masses of cells that form on the lining of the colon. Most colon polyps are benign. But over time, some colon polyps can develop into colon cancer, which is often fatal when found at an advanced stage. So which types of colon polyps are more likely to progress to cancer?

Familial polyposis (FAP) is an inherited disease caused by an abnormality in the APC gene structure. The disease manifests with many polyps growing mainly in the colon, even the duodenum and small intestine. If left untreated, polyps can become cancerous.
