What is a Colonoscopy?
A colonoscopy is an examination using a small flexible camera inserted through the anus to inspect the entire colon. The tip of the scope has a high-resolution video camera that sends images to a monitor, allowing the doctor to detect abnormalities such as
- Polyps in the colon
- Ulcers in the colon
- Inflammation of the colon
- Bleeding in the colon
- Early-stage colorectal cancer
In some cases, the doctor can immediately remove polyps during the colonoscopy, which helps reduce the risk of cancer in the future
Medical Research on Colonoscopy
Research from the New England Journal of Medicine and the American Gastroenterological Association found that colonoscopy can reduce colorectal cancer mortality by approximately 60–70% because it can
- Detect cancer at an early stage
- Detect polyps before they become cancerous
- Remove polyps immediately during the examination
Another study from the U.S. Preventive Services Task Force (USPSTF) recommends that people start colorectal cancer screening from age 45 and above because this is the age when risk begins to increase
