Our gastroenterologists perform colonoscopies to look inside the large intestine (or large bowel) for signs of colorectal cancer.
During a colonoscopy, we insert a colonoscope (a long, flexible lighted tube with an attached camera) into the rectum. Then, we inspect the internal lining of the colon for polyps, ulcers or other abnormalities. If polyps exist, we may remove them via a polypectomy.
In addition to detecting cancer, a colonoscopy helps us evaluate symptoms, such as abdominal pain, rectal bleeding, constipation, diarrhea or a change in bowel habits. We may also use this procedure to perform a biopsy, in which we collect samples of tissues or cells for further analysis.
