Anal cancer information

What is anal cancer?

Anal cancer is a rare form of cancer that develops in the tissues of the anus, which is the opening at the end of the rectum through which stool passes. The anus consists of the outer layers of skin and the large intestine. The anal canal is shaped like a tube and is controlled by muscles that open and close.

Anal cancer incidence

Anal cancer accounts for about 2.4 percent of digestive system cancers, which include colorectal, pancreatic and liver cancers. About one in 600 men and women will develop anal cancer during their lifetime.

An estimated 7,060 cases of anal cancer were diagnosed in 2013, according to the American Cancer Society. Of those cases, approximately 4,430 were in women and 2,630 were in men. While anal cancer is far less common than colorectal cancer, the number of cases has been growing due to human papillomavirus (HPV) infections. HPV is the most common sexually transmitted infection and is responsible for 86-97 percent of anal cancer cases.
