Anal Cancer

Anal cancer is a rare cancer affecting the anal region. It accounts for less than 5% of cancers involving the large intestine.

It presents with a mass at the anal opening accompanied by rectal bleeding. In addition, pain and difficulty in passing a bowel movement may also be present. It is diagnosed by a physical examination and appropriate biopsies.

Depending on the type of anal cancer, the treatment varies. The most common form of anal cancer is treated with chemotherapy and radiation therapy and close follow up. Failure to respond to this treatment may result in surgery. Surgery usually involves the removal of the rectum and anus, resulting in a permanent colostomy.
