A colonoscopy is a diagnostic procedure that allows a doctor to view the inside of the colon using a thin, flexible tube with a small camera attached. It is commonly used to investigate digestive symptoms and screen for colorectal cancer.
During the procedure, the colonoscope is gently inserted through the rectum and guided through the colon. The camera sends real-time images to a monitor, allowing the doctor to identify abnormalities such as polyps, bleeding, or inflammation. If needed, tissue samples can be collected for further testing.
