Your doctor has suggested that you have a colonoscopy as part of your evaluation at National Jewish Health. A colonoscopy allows the doctor to look inside the colon, or large intestine, using a small flexible tube. Your doctor may also do a biopsy and remove any polyps (small growths) he/she finds during the procedure. A biopsy is a small amount of tissue taken from the lining of your colon which can be studied closely to help determine your diagnosis and how best to treat you.
