What is HPV?
Cervical cancer (which the American Cancer Society says affected an estimated 11,150 women in 2007) is by far the most significant concern. However, high-risk types of HPV also have been linked to less-common cancers of the vulva (3,490 women), vagina (2,140 women), anus (2,750 women and 1,900 men) and penis (1,280 men).
