A colonoscopy is a diagnostic test used to see abnormalities and changes in the large intestine and rectum. During this examination, a long flexible tube with a camera attached at its end (colonoscope) is inserted into the patient's rectum, and the doctor visualizes the entire colon. If needed, a polyp can be removed, and tissues can be collected for biopsy.
