Colorectal Polyps

Polyps are commonly found during routine screening exams of the colon and rectum, occurring in approximately 20 percent to 30 percent of American adults. Polyps are abnormal growths arising from the inner lining of the colon or rectum. Some polyps are flat; others have a stalk.

Polyps can occur throughout the large intestine, but are more commonly found in the left colon, sigmoid colon and rectum. The large majority of polyps will not become cancers; however, certain types of polyps are precursors to cancer development. Removal of polyps during colonoscopy reduces the risk of developing colorectal cancer in the future.
