A colon polyp is an abnormal growth of tissue in the lining of the bowel. Polyps are a risk factor for colon cancer.
Colonoscopic polypectomy (colon polyp removal) is the removal of polyps by using a device inserted through a colonoscope.
Most colorectal polyps are adenomas, which may develop into cancer. Removing colorectal polyps that are larger than 1 centimeter (cm) may lower the risk of colorectal cancer. It is not known if removing smaller polyps lowers the risk of colorectal cancer.
