Most cervical cancers are caused by human papillomavirus (HPV), a common virus that is passed from person to person during sex. Two screening tests can help prevent cervical cancer. The Pap test looks for cell changes on the cervix that might become cervical cancer if they are not treated, and the HPV test looks for the virus that can cause these cell changes. HPV vaccines can protect women against the types of HPV that cause most cervical cancers. When cervical cancer is found early, it is highly treatable. The most important thing you can do to help prevent cervical cancer is to get screening tests regularly starting at age 21.
