A colonoscopy is a physical examination of the large intestine and rectum. Colonoscopies help doctors to investigate unexplained changes in a patientâs bowel habits, weight loss and abdominal pain. They are also used to screen for cancer. During the examination, a tube with a camera attached is inserted into the rectum. This camera allows the doctor to examine the patientâs colon, take biopsies and see to any polyps that need removing. A patient is usually sedated while having a colonoscopy.
