The short answer
Cervical cancer screening uses the Pap test, the HPV test, or both to find early cell changes before they can become cancer. Most guidance recommends screening from about age 21 to 65, with the interval depending on the test used. The HPV vaccine complements screening but does not replace it.
Screening uses the Pap test, the HPV test, or both to catch problems early.
Most guidance recommends screening from about age 21 through 65.
How often you screen depends on your age and which test is used — often every 3 to 5 years.
Many people over 65 with a long history of normal results can stop screening.

This page explains cervical cancer screening in plain words. It covers which tests are used, when to start and stop, how often to go, and what an abnormal result means.
What cervical cancer screening is
Cervical cancer screening looks for early cell changes on the cervix, before they can ever become cancer. It uses the Pap test, the HPV test, or both together. The CDC says the earlier cervical cancer is found, the easier it is to treat. Precancer found by a Pap test can be treated, and treatment prevents cervical cancer from developing in most cases.
Screening finds cervical changes early, when they're easiest to watch or treat.
When to start
Most guidance, including from the CDC, recommends starting Pap tests at age 21. If your result is normal, your doctor may tell you that you can wait three years until the next one.
Between the ages of 30 and 65, you generally have three recommended options:
- HPV test alone (primary HPV testing) — if normal, next screening in about 5 years
- HPV test with a Pap test (co-testing) — if both normal, about 5 years
- Pap test alone — if normal, about 3 years
Your care team can help you decide which option fits you best.
Screening usually begins at 21, with more options opening up from age 30 onward.
How often, and why the gaps are safe
The intervals above may seem long. They apply when your results are normal. A normal result does not rule cancer out.
Some symptoms should be looked at rather than waiting for the next test. NCI lists bleeding after sex, bleeding after menopause, heavier or longer periods or bleeding between periods, unusual vaginal discharge, and pain in the pelvis or during sex. Many other conditions can cause these. Call your doctor promptly if you have them. Screening is for people without symptoms.
Keep up regular checkups between screenings. If you've had abnormal results before, you may be advised to screen more often.
Intervals are for people with normal results and no symptoms. Keep up regular checkups.
When you can stop
After age 65, your doctor may tell you that you no longer need screening if:
- You've had several normal results over the past 10 years (for example, three normal Pap tests or two normal HPV tests)
- You have no history of high-grade precancer (CIN 2, CIN 3, or AIS) or cervical cancer
- You have no ongoing risk factors
Some people have had their cervix removed as part of a total hysterectomy for a reason such as fibroids. They may also be able to stop, but only if they never had high-grade precancer (CIN 2, CIN 3, or AIS) or cervical cancer. Precancer is not cancer, so "the surgery was not for cancer" is not enough on its own. If your cervix was left in place, or you are not sure what your records say, keep screening until your care team checks.
How the HPV vaccine and screening work together
The HPV vaccine does not prevent every high-risk type of HPV. NCI says vaccinated people with a cervix should still follow the standard screening schedule.
The HPV vaccine complements screening — it doesn't replace it.
What abnormal results mean
An abnormal result means cell changes were found on your cervix. The CDC says this usually does not mean cancer. It can take as long as three weeks to get results. Follow up with your doctor right away to learn more and get any treatment you need. Your doctor may suggest more testing, such as a colposcopy.
Getting screened if cost is a concern
Is cost a concern? The CDC offers free or low-cost cervical cancer screening through the National Breast and Cervical Cancer Early Detection Program for those who qualify.
If cost is a barrier, ask about programs that offer free or low-cost cervical screening.

Common questions
When should I start cervical cancer screening?
Guidance from groups like the CDC recommends starting Pap tests at age 21. If your Pap result is normal, your doctor may tell you that you can wait three years until the next test. Different groups set slightly different ages and intervals. NCI notes that the American Cancer Society suggests starting at 25 with HPV testing. Use the schedule your own clinician follows.
What are my options between 30 and 65?
From about age 30 to 65 there are three recommended options: an HPV test alone (primary HPV testing), an HPV test with a Pap test (co-testing), or a Pap test alone. With a normal HPV test or co-test, the next screening may be about five years away; with a Pap test alone, about three years. Your doctor can help you choose.
When can I stop screening?
After age 65, your doctor may say you no longer need screening if you have had several normal results in the past 10 years, no history of high-grade precancer or cervical cancer, and no ongoing risk factors. The usual stopping rules do not apply to some people, including those with a weakened immune system or HIV, exposure to DES before birth, or a history of high-grade precancer or cervical cancer. Ask your care team how often you need testing. People who've had the cervix removed in a total hysterectomy may also be able to stop, but only if they never had high-grade precancer or cervical cancer. Discuss your situation with your care team.
How often do I need to be screened?
It depends on your age and which test is used. Common intervals are every three years for a Pap test alone and every five years for HPV testing or co-testing when results are normal. These intervals apply when results are normal. If you have had abnormal results, you may be told to test more often.
Does the HPV vaccine mean I can skip screening?
No. The HPV vaccine doesn't prevent every high-risk HPV type. Even people who've been vaccinated still need regular screening. Vaccination and screening together give the strongest protection.
What if my result is abnormal?
An abnormal result means cell changes were found on your cervix. The CDC says this usually does not mean you have cervical cancer. Follow up with your doctor right away to learn more and get any treatment you need. Depending on the result, that may include more testing, such as a colposcopy.
