How well do colonoscopies detect cancer?
Colonoscopy is a medical procedure that allows a physician, typically a gastroenterologist, to examine the inner lining of the colon (large intestine) and rectum using a long, flexible tube called a colonoscope. The colonoscope is equipped with a light and a camera, enabling the physician to visualize the entire colon and identify any abnormalities, such as polyps or tumors.
