The highest-risk types are HPV 16 and 18; these are responsible for the vast majority of HPV-related cancers, including cancers of the cervix, vagina, vulva, penis, anus, and head and neck.
The cause of CIN is chronic infection of the cervix with HPV, especially infection with high-risk HPV types 16 or 18. It is thought that the high-risk HPV infections have the ability to inactivate tumor suppressor genes such as the p53 gene and the RB gene, thus allowing the infected cells to grow unchecked and accumulate successive mutations, eventually leading to cancer.
