If your mental model is "a Pap smear every year," you're working from outdated rules. Cervical cancer screening has changed a lot, and for most people it now happens far less often than it used to — not to cut corners, but because we understand the disease better. Here's how often you actually need one, by age.
A quick note before the numbers: these are the guidelines for people at average risk. If you've had abnormal results, a weakened immune system, or certain other history, your schedule is different — more on that below. And your own provider's read on your history always wins over a general rule.
The short version
- Under 21: no screening at all.
- Ages 21 to 29: a Pap test every 3 years.
- Ages 30 to 65: a Pap and HPV test together (co-testing) every 5 years, or a Pap alone every 3 years.
- Over 65: you can usually stop, if your prior screening was adequate and normal.
Now the details.
Under 21: don't screen
Even if you're sexually active, screening before 21 isn't recommended. Cervical changes in this age group almost always clear on their own, and screening tends to lead to procedures that cause more harm than benefit. The only exceptions are specific high-risk situations your provider would flag.
Ages 21 to 29: every 3 years
In your 20s, the recommendation is a Pap test (cervical cytology) every 3 years. HPV testing generally isn't used on its own here, because HPV is extremely common in this age group and usually clears without causing problems — testing for it would trigger a lot of unnecessary follow-up.
Ages 30 to 65: every 3 to 5 years
For this age group, the guidelines we follow (ASCCP) give two screening options:
- A Pap and HPV test together — co-testing — every 5 years.
- A Pap test alone every 3 years.
Co-testing every 5 years is the common choice, because adding the HPV result is what safely stretches the interval out to five years. (You may have seen headlines about an HPV test on its own; that isn't part of the practice guidelines we follow, so we stick with co-testing or cytology.)
Over 65: usually done
If you're past 65 and your previous screenings were adequate and normal — and you don't have a history of higher-grade cervical changes — you can generally stop. If your screening history is incomplete or unknown, it may make sense to keep going for a while. That's a per-person decision.
After a hysterectomy
If you had a total hysterectomy (cervix removed) for a non-cancer reason, you typically don't need cervical screening at all. If your cervix was left in place, or the surgery was for cervical or uterine cancer or precancer, screening continues. We get into this more on our Pap and well-person care page.
When you need them more often
The intervals above are for average risk. You may need more frequent screening if you:
- Have had an abnormal Pap or HPV result, or treatment for cervical changes.
- Have a weakened immune system (including HIV) or take immune-suppressing medication.
- Were exposed to DES before birth.
In these situations the 3-to-5-year intervals don't apply, and your provider will set a schedule based on your specifics.
"Wait, why so infrequent?"
It can feel strange to be told that less screening is better — we're used to assuming more is safer. But cervical cancer is slow-growing and almost always driven by persistent HPV infection. Longer intervals with the right test catch the meaningful changes while sparing people the anxiety, cost, and procedures that come from chasing findings that would have resolved on their own. This is evidence, not economizing.
Already vaccinated against HPV?
Good — and you still follow the same screening schedule. The HPV vaccine dramatically lowers risk but doesn't cover every cancer-causing type, so vaccinated people are screened on the same timeline as everyone else.
Not sure where you stand?
If you can't remember your last Pap — or you're not even sure your last visit included one (it's a surprisingly common mix-up) — that's an easy thing to sort out. Book a Pap and well-person visit or call (301) 241-8181, and if the exam is something you dread, ask about comfort and sedation options.
