Understanding the Guidelines for Stopping Pap Smears
Routine Pap smear screening is a cornerstone of women's preventive healthcare, but it is not a lifelong requirement. The decision to stop screening is based on a combination of age, past screening history, and individual risk factors for cervical cancer. For the vast majority of women, the age of 65 is the key threshold, provided specific criteria are met.
The Standard Cutoff: Age 65
Most major health organizations, including the U.S. Preventive Services Task Force (USPSTF) and the American Cancer Society (ACS), advise that routine cervical cancer screening can often stop at age 65. This recommendation stems from the understanding that cervical cancer typically develops very slowly. For older women with consistent, normal screening histories, the risk of new significant cell abnormalities is low.
Key criteria to be eligible to stop screening at 65 include:
- Adequate Prior Screening: This generally means three consecutive negative Pap tests or two consecutive negative co-test (Pap and HPV test) results within the past 10 years.
- No High-Risk History: No history of a high-grade precancerous lesion (CIN2 or higher) or cervical cancer within the last 25 years is required.
Who Should Continue Screening After 65?
While 65 is a common guideline, certain factors necessitate ongoing screening past this age.
High-Risk Factors That Extend Screening
Continued screening after 65 is typically recommended for women with:
- History of High-Grade Lesions or Cancer: Screening should continue for at least 25 years after treatment for a high-grade lesion or cervical cancer.
- Compromised Immune System: Conditions like HIV or immunosuppressive therapy increase risk and require continued screening.
- DES Exposure: Women whose mothers used DES during pregnancy need continued screening due to increased risk of abnormalities.
How a Hysterectomy Affects Screening
The need for Pap smears after a hysterectomy (removal of the uterus) depends on whether the cervix was removed and the reason for the surgery.
- If the cervix was removed for benign reasons, routine Pap testing is usually no longer needed.
- If the hysterectomy was due to cervical cancer or high-grade precancerous cells, continued screening with vaginal cytology may be necessary.
The Changing Landscape: The Role of HPV Testing
HPV testing has become integral to cervical cancer screening, particularly for women aged 30 to 65, often in combination with a Pap test (co-testing). This can allow for longer screening intervals. HPV vaccination is also influencing future guidelines.
Comparison of Major Screening Guidelines
Screening guidelines can differ slightly between organizations. Discuss these variations with your healthcare provider for personalized recommendations.
| Feature | American Cancer Society (ACS) | U.S. Preventive Services Task Force (USPSTF) |
|---|---|---|
| Age to Begin Screening | Age 25 | Age 21 |
| Screening Age 21-29 | No screening recommended | Pap test every 3 years |
| Screening Age 30-65 | HPV test every 5 years (preferred); Co-testing every 5 years (acceptable); Pap test every 3 years (acceptable) | Pap test every 3 years OR HPV test every 5 years OR Co-testing every 5 years |
| Stopping Screening (Age 65+) | Yes, if adequate negative screening history and no high-risk history | Yes, if adequate negative screening history and no high-risk history |
Importance of Shared Decision-Making with Your Doctor
The decision to stop or continue screening should always be made with your healthcare provider. They can assess your individual health history, past results, and risk factors to provide the best guidance.

Life After Pap Smears
Stopping Pap smears at 65 does not mean the end of all women's health check-ups. Regular pelvic exams and other recommended screenings should continue as part of routine healthcare for older adults.
Conclusion: More Than Just a Number
The answer to what is the cut off age for Pap smears involves more than a simple age. For most women meeting specific criteria, age 65 is the point to consider stopping routine screening. However, individual history and risk factors are paramount, emphasizing the need for discussion with a healthcare provider to ensure appropriate preventive care.
