Cervical Cancer Screening and Prevention
Screening tests
Cervical cancer screening effectively prevents cervical cancer and deaths from the disease. Cervical cancer screening is recommended for everyone with a cervix starting at age 21 to 25 years. Screening tests are usually done every 3 to 5 years, depending on the person's age and the type of test. Two types of tests are used to screen for cervical cancer: HPV test:A sample from the cervix is tested to determine whether the HPV strains that cause most cervical cancers are present. Pap test:Cells from the cervix are examined under a microscope to determine whether any are cancerous or abnormal. Abnormal cells may, without treatment, progress to cancer (these cells are called precancerous cells). Screening may stop after age 65 years, but only if an adequate number of test results have been normal in the preceding 10 years. If women have had a total hysterectomy (surgical removal of the uterus, including the cervix) and have not had cervical cancer or precancer, they do not need to have HPV or Pap tests. The number of deaths due to cervical cancer has been reduced by more than 50% since Pap tests were introduced in countries where Pap tests are available. If all women had cervical cancer tests as recommended, deaths due to this cancer could be virtually eliminated. However, in the United States, many women are not tested regularly, and in middle- and low-resource countries, cervical cancer screening is often not available. The number of deaths due to cervical cancer have decreased by more than 50% since Pap tests were introduced in countries where these tests are available. If all women had HPV and/or Pap tests regularly, deaths due to this cancer could be virtually eliminated. Getting vaccinated against HPV helps prevent cervical cancer.
