A colonoscopy is a crucial exam used to detect changes or abnormalities in the large intestine (colon) and rectum. During a colonoscopy, a long, flexible tube (colonoscope) is inserted into the rectum. A high-definition video camera at the tip of the tube allows the specialist to inspect the entire colon.
Why Is It Done?
Your doctor may recommend a colonoscopy to:
- Screen for colon cancer: Recommended for individuals 45 years or older, or earlier if you have family history or high-risk factors. Colonoscopy is considered the gold standard screening test because polyps can be removed during the procedure before they turn into cancer.
- Investigate intestinal symptoms: Helps discover the root causes of unexplained abdominal pain, rectal bleeding, chronic diarrhea, or unexpected anemia.
- Follow up on polyps: Periodic surveillance ensures complete colon wellness and prevents recurrences.
