What is a colon nodule?
During a colonoscopy today the gastroenterologist found a nodule, which he biopsied and sent to pathology. I asked if a nodule was a polyp (which I`ve had on a previous colonoscopy) and was told hat it was not the same thing. Can you tell me what a nodule is?
A "nodule" on colonoscopy usually describes something smooth that appears to lie just under the lining of the colon. A polyp, on the other hand, arises from the lining of the colon and is bumpy of adenomatous in its appearance.
