Hello,
Virtually all cervical cancers are caused by HPV infections, with just two HPV
types, 16 and 18, responsible for about 70 percent of all cases. HPV also causes anal cancer, with about 85 percent of all cases caused by HPV-16. HPV types 16 and 18 have also been found to cause close to half of vaginal, vulvar, and penile cancers. Other than that, HPV infections have been found to cause cancer of the oropharynx.
