Polyps of the Colon and Rectum
Key Points
Colonic polyps are common; the incidence ranges from 7 to 50% (depending on the diagnostic method used). The main concern is malignant transformation, which occurs at different rates depending on the size and type of polyp. The main symptom is bleeding, usually occult and rarely massive. Colonoscopy is the recommended diagnostic and therapeutic procedure.
