Colon polyps. Section through a gross specimen of the colon (part of the large intestine) showing a large number of polyps (growths). Small numbers of polyps are common in the intestine and they are usually benign (non-cancerous). However, large numbers of polyps increase the chance that some of them will undergo malignant (cancerous) change.
