Anal cancer is a rare type of cancer that affects the anus (the end of the bowel). The anal canal is a short tube at the end of your rectum through which stool leaves the body. Anal cancer can cause signs and symptoms such as rectal bleeding and anal pain.

SYMPTOMS OF ANAL CANCER

Anal cancer signs and symptoms include:

• Bleeding from the anus or rectum
• Pain in the area of the anus
• A mass or growth in the anal canal
• Anal itching

CAUSES OF ANAL CANCER 

Anal cancer forms when a genetic mutation turns normal, healthy cells into abnormal cells. Healthy cells grow and multiply at a set rate, eventually dying at a set time. Abnormal cells grow and multiply out of control, and they don't die. The accumulating abnormal cells form a mass (tumor). Cancer cells invade nearby tissues and can separate from an initial tumor to spread elsewhere in the body (metastasize).

Anal cancer is closely related to a sexually transmitted infection called human papillomavirus (HPV). Evidence of HPV is detected in the majority of anal cancers. HPV is thought to be the most common cause of anal cancers.

RISK FACTORS

Several factors have been found to increase the risk of anal cancer, including:

• Older age. Most cases of anal cancer occur in people age 50 and older.
• Many sexual partners. People who have many sexual partners over their lifetimes have a greater risk of anal cancer.
• Anal sex. People who engage in receptive anal sex have an increased risk of anal cancer.
• Smoking. Smoking cigarettes may increase your risk of anal cancer.
• History of cancer. Those who have had cervical, vulvar or vaginal cancer have an increased risk of anal cancer.
• Human papillomavirus (HPV). HPV infection increases your risk of several cancers, including anal cancer and cervical cancer. HPV infection is a sexually transmitted infection that can also cause genital warts.
• Drugs or conditions that suppress your immune system. People who take drugs to suppress their immune systems (immunosuppressive drugs), including people who have received organ transplants, may have an increased risk of anal cancer. HIV — the virus that causes AIDS — suppresses the immune system and increases the risk of anal cancer.

COMPLICATIONS

Anal cancer rarely spreads (metastasizes) to distant parts of the body. Only a small percentage of tumors are found to have spread, but those that do are especially difficult to treat. Anal cancer that metastasizes most commonly spreads to the liver and the lungs.

PREVENTION

There is no sure way to prevent anal cancer. To reduce your risk of anal cancer:

• Practice safer sex. Practicing safe sex may help prevent HPV and HIV, two sexually transmitted viruses that may increase your risk of anal cancer. If you choose to have anal sex, use condoms.
• Get vaccinated against HPV. A vaccine to protect against HPV infection is available. It's recommended for adolescents, including both boys and girls, but may be given to adults, too.
• Stop smoking. Smoking increases your risk of anal cancer. Don't start smoking.
