Routine Pap Testing Should Stop at Age 65
Women should discontinue cervical cancer screening after age 65 if they have had adequate prior screening: either ≥3 consecutive negative Pap tests OR ≥2 consecutive negative HPV and Pap co-tests within the last 10 years, with the most recent test occurring within the last 5 years 1.
Key Criteria for Stopping at Age 65
The decision to stop screening is not based solely on reaching age 65—it requires documented adequate prior screening:
- Option 1: Three consecutive negative Pap tests within the past 10 years
- Option 2: Two consecutive negative HPV/Pap co-tests within the past 10 years
- Critical requirement: The most recent test must have occurred within the last 5 years
Once screening is discontinued after meeting these criteria, it should not resume for any reason, including if a woman has a new sexual partner 2.
Important Exceptions—Continue Screening Beyond Age 65
Several groups should continue screening past age 65:
1. History of High-Grade Lesions
Women with a history of CIN2, CIN3, or adenocarcinoma in situ (AIS) should continue surveillance for at least 25 years after treatment, even if this extends screening well past age 65 3. This is based on long-term follow-up data showing persistent elevated risk.
2. Inadequate Prior Screening
Women who do not meet the adequate screening criteria listed above should continue screening until they achieve the required negative test history 2, 4. This is a critical pitfall—approximately 18.4% of women aged 61-65 reach the "stopping age" without adequate prior screening 4.
3. High-Risk Populations
Continue screening indefinitely for women who are:
- HIV-positive
- Immunocompromised (organ transplant, chronic corticosteroids, chemotherapy)
- History of in utero DES exposure
- History of cervical cancer 2, 5
4. Post-Hysterectomy Exception
Women who had a hysterectomy for CIN2/3 or cancer should continue screening for 20 years post-treatment, regardless of age 2.
Clinical Considerations and Common Pitfalls
The biggest challenge: Many women lack documentation of adequate prior screening 4. In the absence of screening registries and shared medical records in the U.S., if you cannot document adequate prior screening, perform screening tests until criteria are met 3.
The evidence on stopping at 65: Modeling data shows that extending screening from age 65 to 70 confers only 0.4% additional life-years gained, with a 3% increase in colposcopies required 3. The absolute benefit is minimal when adequate prior screening is documented.
The reality of cervical cancer burden in older women: Approximately one-third of cervical cancers occur after age 65 6, and incidence rates don't decline until age ≥85 when corrected for hysterectomy status 4. However, most of these cases occur in women who were inadequately screened before age 65 4, 7.
What About Women Who Have Had a Total Hysterectomy?
Women who have had a total hysterectomy (cervix removed) for benign reasons should stop cervical cancer screening entirely 1. The exception is women with a history of high-grade dysplasia or cervical cancer—they need continued surveillance as noted above.
The Bottom Line Algorithm
Age <65: Continue routine screening per guidelines (every 3 years with Pap alone or every 5 years with HPV/Pap co-testing for ages 30-65) 1
Age ≥65 with adequate screening: Stop screening
Age ≥65 without adequate screening: Continue screening until adequate negative history is achieved
Any age with high-risk history: Follow extended surveillance protocols regardless of age
