Anal Cancer Directory

Anal cancer is a rare type of cancer that starts in the anus, the opening at the end of the rectum. When it is found early, anal cancer is highly treatable. Anal infection with the human papillomavirus (HPV) is a major risk factor for anal cancer. Other risks include being over age 50, having many sexual partners, receiving anal sex, and having a weak immune system. Some people have no symptoms. However, when symptoms are present, anal bleeding is usually the first sign of the disease.
