What is a viral cause of cervical cancer?

When you’re exposed to genital human papillomavirus (HPV), your immune system usually prevents the virus from doing serious harm. But sometimes, the virus survives for years. Eventually, the virus can lead to the conversion of normal cells on the surface of the cervix into cancerous cells.

Which virus has been linked to cervical cancer?

HPV can cause cervical and other cancers including cancer of the vulva, vagina, penis, or anus. It can also cause cancer in the back of the throat, including the base of the tongue and tonsils (called oropharyngeal cancer). Cancer often takes years, even decades, to develop after a person gets HPV.
