human papillomavirus

(HYOO-mun PA-pih-LOH-muh-VY-rus)
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. Human papillomavirus infections can cause abnormal tissue growth, such as skin warts or genital warts, and other changes to cells, including cancer. Although most human papillomavirus infections go away on their own and do not cause cancer, infection with certain types of human papillomavirus can last for many years and, if not treated, may become cancer. Human papillomavirus-related cancers include cancers of the cervix, anus, oropharynx, vagina, vulva, and penis. Also called HPV.
