Cervical Cancer: Cervical cancer can be detected with routine cervical cancer screening (Pap test) and follow-up of abnormal results. The Pap test can find abnormal cells on the cervix so that they can be removed before cancer develops. Abnormal cells often become normal over time, but can sometimes turn into cancer. These cells can usually be treated, depending on their severity and on the woman’s age, past medical history, and other test results. An HPV DNA test, which can find certain HPV types on a woman's cervix, may also be used with a Pap test in certain cases (called co-testing). Even women who were vaccinated when they were younger need regular cervical cancer screening because the vaccines do not protect against all cervical cancers.
