Anorectal Disorders
Anal cancer occurs when cancer cells form within the tissues of the anus. The anal canal or anus is a short tube at the end of large intestine and below the rectum through which stool leaves the body.
Anal cancer is a rare condition that may produce symptoms such as bleeding from the anus or rectum or a lump that forms in the area. If anal cancer is diagnosed, depending on the stage of the disease, treatment may include radiation, chemotherapy, or surgery.
