Which screening test is recommended for cervical cancer starting at age 21?

The recommended screening test for cervical cancer starting at age 21 is the Pap smear. The Pap smear, also known as a Pap test, is designed to detect precancerous changes in the cervix that could lead to cervical cancer if not treated. Starting at age 21, regardless of sexual history, women are advised to undergo Pap testing every three years until they reach age 29. This guideline is based on evidence that cervical cancer is exceedingly rare in women younger than 21 and emphasizes the importance of early detection in those who are at risk.

While the HPV DNA test is also an important tool in cervical cancer screening, it is typically not recommended for routine screening until age 30, where it can be used alone or in conjunction with the Pap smear. Cervical biopsy is not a screening test and is instead used for diagnostic purposes in cases where abnormal results are found. A transvaginal ultrasound is not a screening test for cervical cancer and is generally utilized for evaluating other gynecological issues. The guidelines specifically endorse the Pap smear as the initial screening test for women beginning at age 21.
