Human Papilloma Virus

Human papillomaviruses (HPVs) are a group of more than 100 related viruses. They are called papillomaviruses because certain types may cause warts, or papillomas, which are benign (noncancerous) tumors. The HPVs that cause the common warts which grow on hands and feet are different from those that cause growths in the throat  or genital area. Some types of HPV are associated with certain types of cancer. These are called high-risk, oncogenic, or carcinogenic HPVs.

Genital HPV infections are very common and are sexually transmitted. Of the more than 100 types of HPV, more than 30 types can be passed from one person to another through sexual contact. Although HPVs are usually transmitted sexually, doctors cannot say for certain when infection occurred. Most HPV infections occur without any symptoms and go away without any treatment over the course of a few years. However, HPV infection sometimes persists for many years, with or without causing cell abnormalities. This can increase a woman’s risk of developing cervical cancer.
