Genital warts can be removed by freezing. [5] Nearly every sexually active individual is infected by HPV at some point in their lives. [4] HPV is the most common sexually transmitted infection (STI), globally. [5] High-risk HPVs cause about 5% of all cancers worldwide and about 37,300 cases of cancer in the United States each year. [10]
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.
HPV types 6 and 11 are responsible for causing majority of genital warts whereas HPV types 16, 18, 31, 33, and 35 are also occasionally found. [5] It is spread through direct skin-to-skin contact, usually during oral , manual , vaginal , or anal sex with an infected partner.
This is associated with carcinogenic genotypes of HPV and/or HPV persistence factors such as cigarette smoking or immunocompromised states. Differentiated vulvar intraepithelial neoplasia also known as VIN Simplex: is associated with vulvar dermatoses such as lichen sclerosus. It is associated with atypia of the squamous epithelium.

HPV is spread by direct and indirect contact from an infected host. Avoiding direct contact with contaminated surfaces such as communal changing rooms and shower floors and benches, avoiding sharing of shoes and socks and avoiding contact with warts on other parts of the body and on the bodies of others may help reduce the spread of infection.
A study of more than 160,000 women in New Mexico published in Preventative Medicine found that between January 2015 and August 2019, only half who tested positive for cancer-causing HPV cells ...
ThinPrep pap smear with group of normal cervical cells on left and HPV-infected cells showing features typical of koilocytes: enlarged (x2 or x3) nuclei and hyperchromasia. A koilocyte is a squamous epithelial cell that has undergone a number of structural changes, which occur as a result of infection of the cell by human papillomavirus (HPV). [1]
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.
