HPV 18

A type of HPV that is transmitted sexually and causes cancers of the cervix, anus, oropharynx (the middle part of the throat, behind the mouth), vagina, vulva, and penis. A long-lasting infection with HPV 18 can cause cell changes that, if not treated, may worsen over time and become cancer. HPV 18 and HPV 16 are responsible for most HPV-related cancers. Also called human papillomavirus 18.
