What is it used for?
An anoscopy is most often used to diagnose:
Hemorrhoids, a condition that causes swollen, irritated veins around the anus and lower rectum. They can be inside the anus or on the skin around the anus. Hemorrhoids are usually not serious, but they can cause bleeding and discomfort.
Anal fissures, small tears in the lining of the anus
Anal polyps, abnormal growths on the lining of the anus
Inflammation. The test can help find the cause of unusual redness, swelling, and/or irritation around the anus.
Cancer. High resolution anoscopy is often used to look for cancer of the anus or rectum. The procedure can make it easier for your health care provider to find abnormal cells.
