What is examined during a colonoscopy?

During a colonoscopy, the medical professional examines the inner lining of the rectum and colon, or large intestine, using a colonoscope. A colonoscopy is a procedure that helps in detecting abnormalities, such as inflammation, ulcers, polyps, or cancer, throughout the colon and rectum. It allows for a visual inspection and enables the removal of suspicious growths or polyps for biopsy or removal if necessary. The entire colon and rectum are closely examined, providing valuable information about the health and condition of the large intestine.
