The USPSTF guidelines recommend screening for cervical cancer every 3 years with a Pap test in women ages 21 to 29 years. For women aged 30 to 65 years, the USPSTF recommends screening every 3 years with cervical cytology (Pap) alone, every 5 years with high-risk human papillomavirus (hrHPV) testing alone, or every 5 years with an hr HPV test combined with cytology. If both methods are used, this is often called cotesting. Women under age 21 or over age 65 may be exempt from screening, but read the details. USPSTF is the US Preventive Services Task Force. The recommendations were updated in 2018, and are still under review as of January 2023. US Preventive Services Task Force.
