Colon polyp. Coloured computed tomography (CT) scan of a section through the abdomen of a patient with a pedunculated (stalked) polyp (upper centre) in the colon (large intestine). Polyps are benign (non-cancerous) growths that arise from mucous membranes. Although benign, polyps are generally removed surgically as their growth may obstruct the passage of food, and some polyps may turn cancerous over time.
