Screening is when a test is used to look for a disease before there are any symptoms. Cancer screening tests are effective when they can find disease early, which can lead to more effective treatment. (Diagnostic tests are used when a person has symptoms. The purpose of diagnostic tests is to find out, or diagnose, what is causing the symptoms. Diagnostic tests also may be used to check a person who is considered at high risk for cancer.)
Of all the gynecologic cancers, only cervical cancer has a screening test—the Pap test—that can find this cancer early, when treatment works best. The Pap test also helps prevent cervical cancer by finding precancers, cell changes on the cervix that might become cervical cancer if they are not treated appropriately. In addition to the Pap test, which is the main screening test for cervical cancer, a test called the HPV test looks for HPV infection. It can be used along with the Pap test for screening women aged 30 years and older. It also is used to provide more information when Pap test results are unclear for women aged 21 and older.

Since there is no simple and reliable way to screen for any gynecologic cancers except cervical cancer, it is especially important to recognize warning signs and learn if there are things you can do to reduce your risk. Talk with your doctor if you believe that you are at increased risk for gynecologic cancer. Ask what you might do to lower your risk and whether there are tests that you should have.
