Pap smears should start at age 21 and continue through age 65, with the type of test and how often you need it changing as you get older. Screening before 21 is not recommended, even if you’re sexually active. Here’s how the schedule works at each stage.
Ages 21 to 29: Pap Smear Every 3 Years
Your first Pap smear should happen at age 21. From there, you need one every three years as long as your results come back normal. During this age range, the standard test is a Pap smear alone, which collects cells from your cervix to check for precancerous changes.
HPV testing on its own is not recommended for this age group. HPV infections are extremely common in your twenties, and most clear on their own without ever causing problems. Testing for HPV at this age would flag infections that will likely resolve, leading to unnecessary follow-up procedures and anxiety. The Pap smear catches the rare cases where an infection has actually started to change cervical cells.
Ages 30 to 65: More Testing Options
Once you turn 30, you have three choices for cervical cancer screening:
- HPV test alone every 5 years
- HPV test plus Pap smear together (called co-testing) every 5 years
- Pap smear alone every 3 years
The reason HPV testing becomes an option at 30 is that persistent HPV infections at this age are more likely to be clinically significant. An HPV infection that hasn’t cleared by your thirties carries a higher risk of eventually causing cervical changes, so detecting it has real value. Any of the three options is considered acceptable, and which one you get often depends on what your provider’s office offers and what your insurance covers.
If you choose one of the five-year options and your results are normal, you genuinely can wait the full five years before your next screening. That longer interval is safe because cervical cancer develops slowly, typically over 10 to 20 years from initial HPV infection to cancer.
After Age 65: When You Can Stop
Screening is no longer recommended after 65 if you have a history of adequate prior screening and normal results, and you’re not at high risk for cervical cancer. “Adequate prior screening” generally means a consistent track record of normal tests over the previous decade.
If you haven’t been screened regularly, or if you’ve had abnormal results in recent years, your provider will likely recommend continuing past 65. The guideline assumes a clean screening history, not just reaching a birthday.
Why Some Guidelines Say Age 25
You may see conflicting information online because the American Cancer Society updated its guidelines to recommend starting screening at age 25 with an HPV test instead of a Pap smear. However, the U.S. Preventive Services Task Force and the American College of Obstetricians and Gynecologists still recommend starting at 21 with a Pap smear.
The ACS reasoning reflects rising HPV vaccination rates. As more people enter their twenties already vaccinated, the number of cervical abnormalities found between ages 21 and 24 has dropped, making screening in that window less productive. But ACOG has raised a practical concern: screening rates are already lowest among people under 30, and pushing the start age to 25 could worsen that gap. It could also deepen existing health inequities, since vaccination rates aren’t uniform across all communities. For now, most providers follow the age-21 recommendation.
Screening After a Hysterectomy
Whether you still need Pap smears after a hysterectomy depends on what was removed and why. If you had a total hysterectomy (uterus and cervix both removed) for a reason unrelated to cancer or precancerous cells, you no longer need cervical screening. If the surgery was done because of cancer or a high-grade precancerous lesion, you’ll still need follow-up screening on a schedule your provider sets.
If you had a partial hysterectomy that left your cervix in place, the standard screening schedule still applies to you.
If You Have HIV or a Weakened Immune System
People with HIV follow a more frequent screening schedule. Screening still starts at age 21, but Pap smears are done yearly rather than every three years. After three consecutive normal annual results, the interval can be extended to every three years. Starting at age 30, co-testing (HPV test plus Pap smear) becomes an option, again done yearly until three consecutive normal results allow spacing it out.
One major difference: people with HIV should continue screening for life rather than stopping at 65. A suppressed immune system means HPV infections are less likely to clear on their own and more likely to progress, so the protection of ongoing screening remains valuable at any age.
How to Prepare for Your Appointment
A few things can interfere with your Pap smear results. For the most accurate test, schedule your appointment for after your period has ended. Avoid vaginal sex for two days before the exam, and don’t use tampons, vaginal creams, lubricants, douches, or spermicidal foams or jellies for at least two days beforehand. These products can wash away or obscure the cervical cells the test is trying to collect.
The test itself takes only a few minutes. Your provider inserts a speculum, gently collects a small sample of cells from your cervix with a soft brush, and sends them to a lab. You may feel brief pressure or mild discomfort, but it shouldn’t be painful. Results typically come back within one to three weeks.
