The best way to reduce the risk of developing anal cancer is to avoid infection with HPV or HIV. The risk of these infections is higher for those who have sex with multiple partners and those who have unprotected anal sex.

	Can anal cancer be prevented.Therefore,Since the cause of many cases of anal cancer is known that the disease can be prevented completely. The best way to reduce the risk of anal cancer is to prevent infection with HPV or HIV. The risk of these infections is greater for those who have sex with multiple partners and having unprotected anal sex. HPV infection increases the risk of anal cancer. HPV infection may be present for years without symptoms, so the absence of visible warts can not be used to find out if someone has HPV. Even when someone does not have warts (or any other symptom), he (or she) can still be infected with HPV and pass the virus to another person. Condoms ("rubbers") provide some protection against HPV, but can not completely protect against infection. This is because HPV can still be transmitted from one person to another by skin to skin contact with an HPV-infected area of ​​the body not covered by a condom - as the skin in the genital or anal area. However, it is important to use condoms to protect against AIDS and other sexually transmitted diseases are transmitted through certain body fluids. A vaccine called Gardasil ® can help protect against infection with HPV subtypes 16 and 18 (as well as 6 and 11). In studies, this vaccine was found to prevent anal and genital warts caused by HPV types 6 and 11 and to prevent anal cancer, vulvar, vaginal and cervical cancer and precancerous lesions caused by types 16 and 18. This vaccine can only be used to prevent HPV infection - no help treat an existing infection. To be most effective, the vaccine should be administered before a person becomes sexually active. Gardasil was originally approved only for use in women to prevent cervical cancer, but is now also approved to prevent vulvar and vaginal cancers and pre-cancer (in women) and to prevent anal cancer and precancer both men and women. It is also approved to prevent anal and genital warts in men and women. Cervarix ®, another HPV vaccine available in the U.S., can also be used to prevent infection with HPV types 16 and 18, but so far only been shown to help prevent cervical cancer and precancer and not any of the other cancers linked to HPV infection (such as cancer of the anus). Smoking is a known risk factor for anal cancer. Quitting smoking greatly reduces the risk of anal cancer and many other types of cancer.
