Colonoscopy is a specialized endoscopic procedure used to examine the lower part of the digestive tract, including the anus, rectum, colon, and the last part of the small intestine.
It is one of the most important procedures for diagnosing and treating several conditions affecting the large intestine and rectum.
Common Uses of Colonoscopy

Why Colonoscopy Is Important
Colonoscopy is not only a diagnostic tool, but also an effective therapeutic procedure. It plays a major role in the early detection and prevention of colorectal cancer, especially through the detection and removal of polyps before they become cancerous.
