Are vulval cancer and vaginal cancer caused by hpv?

Most likely yes: Hpv is the cause of almost all vulvar and vaginal cancers. There are occasional vulvar melanomas that are probably not caused by hpv. Most of the vulvar and vaginal cancers that are not related to hpv occur in smokers, and are related to nicotine - a known carcinogen. Not surprising is the fact that smokers are more likely to develop hpv related vulvar and vaginal cancers and are harder to cure.

Associated: Hpv is associated with genital areas for warts and cancers in men and women which can include inside into the vagina and cervix and anus. Head and neck linings can also be associated with hpv. What I am saying hpv does not always lead to or cause these cancers and these cancers can occur without hpv. Gardasil vaccines can help prevent hpv.
