Allows your doctor to view the inside of your lower digestive tract (colon & rectum). It can help screen for colon cancer and can also help find the source of abdominal pain, bleeding, and changes in bowel habits. This test can safely be performed in our state-of-the -art center-Queens Endoscopy ASC. During the exam the doctor can remove a small tissue sample (a biopsy) for testing. Small growth such as polyps may also be removed during colonoscopy.
