Definition

A group of viruses that infect the cells on the surface of the skin or on the moist surfaces or inner lining of some organs and body cavities, such as the cervix, vagina, vulva, penis, anus, mouth, and throat. HPV infections can cause abnormal tissue growth, such as skin warts or genital warts, and other changes to cells, including cancer. Although most HPV infections go away on their own and do not cause cancer, infection with certain types of HPV can last for many years and, if not treated, may become cancer. HPV-related cancers include cancers of the cervix, anus, oropharynx, vagina, vulva, and penis. Also called human papillomavirus.
