Colon polyp. Endoscopic view of a hyperplastic (serrated) sessile (non-stalked) polyp (lower right) in a patient's 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.
