Intestinal polyp removal. Endoscope view of a polyp (centre-right) being removed from 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.
