Colon Cancer – Biopsy



So when you’re getting a colonoscopy, the gastroenterologist may find a tumor or a large polyp. At that time, they’ll either determine that the polyp or lesion is resectable, or they may take a biopsy. The biopsy is actually performed with a forceps that has a small claw at the end that actually takes a piece of the polyp or mass. Sometimes they’ll actually perform what’s called a snare polypectomy or a snare biopsy, and this is actually a wire that goes around the polyp and cuts through it and takes a chunk of the polyp or mass off at that time.
