Precancerous polyps are treated by removing tissue samples, determining the type of polyp in the laboratory, and periodic monitoring, according to WebMD. Polyps are benign tissue growths that appear on the wall of the colon that may develop into cancer, explains the American Cancer Society.
The typical treatment procedure for adenomatous polyps is a follow-up colonoscopy every one to three years to monitor for the growth of additional polyps, according to WebMD.
Treatment for familial adenomatous polyposis, also known as FAP, is more extensive because almost all patients with this disease develop cancer of the colon by the time they are 40 years old, reports WebMD. FAP usually requires a total colectomy, which involves surgical removal of a portion of the colon.
