Pap Testing and HPV Screening Age Recommendations
Pap testing for cervical cancer screening should begin at age 21 years, regardless of sexual activity history. 1, 2
Current Age-Based Recommendations
- Screening should begin at age 21 years, regardless of when sexual activity started, according to the American College of Obstetricians and Gynecologists (ACOG) and American Cancer Society (ACS) 2, 1
- For women aged 21-29 years, screening should be performed every 2 years 1, 2
- For women aged 30 years and older with normal results, screening can be extended to every 3 years 1, 2
- Women aged 30 years and older may also opt for HPV co-testing with Pap test every 5 years 1, 3
- Screening may be discontinued at age 65-70 years after 3 consecutive normal tests in the last 10 years 1, 2
HPV Testing Recommendations
- HPV co-testing is not recommended for women under age 30 2
- HPV testing can be used in conjunction with Pap tests for women aged ≥30 years 2
- High-risk HPV DNA tests are recommended for the triage of women aged ≥21 years who have ASC-US (atypical squamous cells of undetermined significance) cytology results 2
- HPV DNA testing is not recommended for women aged <20 years for screening or management of abnormal Pap tests 2
Rationale for Current Age Recommendations
- The incidence of cervical cancer in women younger than 21 years is extremely low (only 0.1% of all cervical cancer cases) 2, 1
- The annual incidence is only 1-2 cases per 1,000 females aged 15-19 years 2, 1
- There are concerns about potential harms from anxiety and unnecessary procedures following positive tests in young women 2, 1
- Most HPV infections in young women are transient and will resolve spontaneously without causing cervical abnormalities 4, 5
Special Considerations
- Women with hysterectomy (with cervix removed) for benign reasons can discontinue screening 1, 2
- Women at high risk (HIV positive, immunocompromised, history of cervical cancer) may require more frequent screening 1, 2
- Women who have received HPV vaccination should still follow the same screening guidelines as unvaccinated women 2, 5
Evolution of Guidelines
- Earlier guidelines (pre-2010) recommended screening approximately 3 years after first vaginal intercourse but no later than age 21 years 2
- Since 2010, major organizations have shifted to recommending starting screening at age 21 years regardless of sexual activity 2, 1
- The American Cancer Society updated their guidelines in 2020 to recommend starting screening at age 25 years, citing the low incidence of cervical cancer in women under 25 1
Common Pitfalls to Avoid
- Do not begin screening before age 21, even in sexually active adolescents 2, 1
- Do not use HPV testing alone as a primary screening test without Pap testing 2
- Do not assume that HPV vaccination eliminates the need for regular screening 5, 2
- Do not screen too frequently, as this can lead to unnecessary procedures with potential harm 2, 6
- Do not discontinue screening prematurely before age 65-70 without adequate prior normal results 2, 1
