A diagnostic colonoscopy is an invasive medical procedure that involves examining the entire length of the large intestine (colon) and rectum using a flexible tube called a colonoscope. The colonoscope is inserted through the anus, and air or carbon dioxide is introduced to expand the colon for better visualization. This procedure helps diagnose and prevent colorectal cancer by detecting precancerous polyps and other abnormalities.
