Pap tests (or Pap smears) look for cancers and precancers in the cervix. Precancers are cell changes that can be caused by the human papillomavirus (HPV). If not treated, these abnormal cells could lead to cervical cancer. An HPV test looks for HPV in cervical cells. Most women 21 to 65 years old need to get Pap tests or a Pap test and HPV test together. Not all women need to be tested every year.
What is a Pap test?
A Pap test is a test your doctor or nurse does to check your cervix for any cells that are not normal. The cervix is the lower part of the uterus (womb), which opens into the vagina. Abnormal cervical cells, if not found and treated, can lead to cervical cancer.
During a Pap test your doctor or nurse puts a speculum (a tool that helps your doctor or nurse see your cervix) into your vagina and uses a special stick or soft brush to collect cells from the outside of your cervix. The cells are sent to a laboratory for testing.
What is an HPV test?
An HPV test looks for DNA from HPV in cells from your cervix. The cervix is the lower part of the uterus (womb), which opens into the vagina. HPV is a sexually transmitted infection (STI) that goes away on its own in most people.1 If it does not go away, HPV can cause abnormal cervical cells that can lead to cervical cancer.
Certain types of HPV are more likely to cause cervical cancer.2 The HPV test can tell your doctor if you have HPV and which type it is.
During an HPV test, your doctor or nurse puts a speculum (a tool that helps your doctor or nurse see your cervix) into your vagina and uses a soft brush to collect cells from the outside of your cervix. The cells are tested in a laboratory.
Pap tests and HPV tests can be done at the same time (called co-testing).
Why do I need a Pap and HPV test?
A Pap test can save your life. It can find cervical cancer cells early. The chance of successful treatment of cervical cancer is very high if the disease is caught early. Pap tests can also find abnormal cervical cells before they become cancer (precancers). Removing these precancers prevents cervical cancer over 95% of the time.3
An HPV test can give your doctor more information about the cells from your cervix. For example, if the Pap test shows abnormal cervical cells, the HPV test can show whether you have a type of HPV that causes cervical cancer.
Who should get regular Pap or HPV tests?
Most women 21 to 65 years old should get Pap tests as part of routine health care. Even if you are not currently sexually active, got the HPV vaccine, or have gone through menopause, you still need regular Pap tests. Experts recommend:4
- Women 21–29 get a Pap test every 3 years
- Women 30–65 get:
- A Pap test every 3 years, or
- An HPV test every 5 years, or
- A Pap and HPV test together (called co-testing) every 5 years
Women older than 65 need a Pap test if they have never been tested, or if they have not been tested after age 60.4
HPV tests are recommended for women 30 and older. Although HPV is common in women younger than 30, it usually goes away on its own in these women. Pap tests combined with HPV tests, or HPV tests alone, are most useful for women 30 and older.4
Who does not need to get regular Pap or HPV tests?
The only women who may not need regular Pap or HPV tests are:4
- Women older than 65 who have had three normal Pap tests or two normal co-tests in a row within the last 10 years, with the most recent test happening within the last 5 years, and who have been told by their doctors that they don’t need to be tested anymore
- Women who do not have a cervix (usually because of a hysterectomy) and who do not have a history of cervical cancer or abnormal Pap test results
Always talk to your doctor or nurse before stopping regular Pap and HPV tests.
I had a hysterectomy. Do I still need Pap and HPV tests?
Even if you have had a hysterectomy, you may need a Pap and HPV test. It depends on the type of hysterectomy you had and your health history. Talk to your doctor or nurse about whether you need Pap and HPV tests.4
- If you no longer have a cervix because you had a hysterectomy for reasons other than abnormal cervical cells or cervical cancer, you do not need Pap and HPV tests.
- If you had a hysterectomy because of abnormal cervical cells or cervical cancer, you should continue to get Pap and HPV tests. Talk to your doctor or nurse about how often you should have Pap and HPV tests.
- If you had your uterus removed but you still have a cervix (this type of hysterectomy is not common), you need regular Pap and HPV tests until you are 65 and have had three normal Pap tests or two normal co-tests in a row within the last 10 years with the last test happening within 5 years.
How often do I need to get a Pap test or Pap and HPV tests together?
It depends on your age and health history. Talk with your doctor or nurse to find out how often you need to get a Pap test or Pap and HPV tests together. Most women can follow these current recommendations from the U.S. Preventive Services Task Force:4
- If you are 21 to 29 years old, you should get a Pap test every 3 years.
- If you are 30 to 65 years old, you should get:
- A Pap test every 3 years, or
- An HPV test every 5 years, or
- A Pap test and HPV test together (called co-testing) every 5 years
- If you are older than 65, ask your doctor whether you can stop having Pap and HPV tests.
Who needs Pap and HPV tests more often?
Your doctor or nurse may recommend getting Pap and HPV tests more often if:4
- You have had treatment for abnormal Pap results or cervical cancer in the past. Women with a medical history of precancerous cells or cervical cancer may need to be tested more often, because their medical history puts them at higher risk in the future.
- You are living with HIV. Women who are living with HIV (the virus that leads to AIDS) are at higher risk of cervical cancer and other cervical diseases because of a weakened immune system. All women living with HIV should get an initial Pap test at the time of the HIV diagnosis and a second Pap test (or Pap and HPV test if you are older than 30) 12 months later. Some experts recommend a second Pap test or Pap and HPV test 6 months later, so talk to your doctor or nurse. After three normal Pap tests in a row, women living with HIV can get follow-up Pap tests every 3 years.5
- Your mother was exposed to diethylstilbestrol (DES) while pregnant with you. Daughters, and possibly granddaughters, of women who took DES while pregnant with them have a higher risk of cervical cancer and some other types of cancer.
- You have a weakened immune system because of organ transplant, chemotherapy, or steroid use. HPV may not go away on its own in a person with a weakened immune system.
Are Pap and HPV tests painful?
Some women find Pap and HPV tests uncomfortable, but the tests should not be painful. You will feel pressure as your doctor or nurse puts the speculum (a tool that helps your doctor or nurse see your cervix) into your vagina.
If you have never had sexual intercourse or if you have had pain when something is put into your vagina, you can ask your doctor or nurse to use a smaller speculum.
You can also help lessen or prevent pain by urinating before the test to empty your bladder or by taking an over-the-counter pain reliever, such as aspirin, acetaminophen, or ibuprofen, about an hour before your Pap or HPV test.
Can I get a Pap or HPV test if I’ve been sexually assaulted in the past?
Yes. If you were sexually assaulted or abused in the past, and this experience makes medical exams difficult for you, talk to your doctor or nurse first.
Before the test, while you are still fully clothed, tell your doctor or nurse that you’ve been assaulted in the past and that you have concerns about the test. It may be difficult to lie on an exam table with your legs in footrests (cradles for your feet that help keep your legs bent and open) or to have a doctor or nurse put a speculum (a tool that helps your doctor or nurse see your cervix) into your vagina. Your doctor or nurse will talk with you about ways to make the Pap or HPV test easier.
How do I prepare for a Pap or HPV test?
You do not have to do anything special to prepare for a Pap or HPV test. Also, you should not douche before a Pap or HPV test. Most doctors do not recommend douching for any reason. You also should not put anything in or around your vagina to clean it, other than soap and water on the outside of your vagina.
Can I get a Pap or HPV test when I am having my period?
Yes, you can get a Pap or HPV test during your period. It’s better to schedule the test for a time when you do not expect to have your period. But it’s also better to get a Pap test at any time than to miss your appointment because of your period.
Depending on how heavy your flow is, your period may affect the results of the Pap or HPV test. If you’re uncomfortable or not sure, call your doctor or nurse before your appointment.
What happens during Pap and HPV tests?
Your doctor or nurse can do a Pap test in the exam room of a doctor’s office. You will lie down on your back on an exam table. You will place your feet on either side of the table in footrests (cradles for your feet that help keep your legs bent and open). Your doctor or nurse will put a tool called a speculum into your vagina (you may feel pressure) and will open it to see your cervix.
Your doctor or nurse will use a special stick or soft brush to take a few cells from the surface of and inside your cervix and vagina. Your doctor or nurse will put the cells on a glass slide or in a small container and send them to a lab for testing. If your doctor or nurse orders an HPV test, the cells taken for your Pap test are tested for HPV at the same time.
Pap and HPV tests usually last about 5 minutes. You may have some spotting (light bleeding from the vagina) afterward.
When will I get my Pap and HPV test results?
Usually, it takes 1 to 3 weeks to get Pap and HPV test results. Most of the time, test results are normal.
If you do not get the results of your Pap and HPV tests 3 weeks after the test, call your doctor’s office to get the results. If the doctor or nurse tells you to schedule another appointment to follow up on abnormal results, be sure to go to the appointment.
What do my Pap test results mean?
Your Pap test results will say one of these three things:
- Normal. The cells collected from your cervix during the Pap test look like they should and you do not have to do anything until your next Pap test.
- Unclear. Your doctor does not know whether the cells collected from your cervix are normal or abnormal. If results are unclear, your doctor may do more testing right away to rule out any problems, or your doctor may have you come back in 6 months or a year for another Pap test.
- Abnormal. The cells collected from your cervix during your Pap test look abnormal. Abnormal Pap test results do not mean you have cancer, so your doctor must do other tests to find out what should happen next. Your doctor may do another Pap test right away or, if the cell changes are minor, wait 6 months or a year before doing another Pap test. If the test finds more serious changes in the cells of your cervix, your doctor will do more tests, such as a colposcopy and biopsy.
What is a colposcopy?
During a colposcopy, your doctor or nurse takes a closer look at abnormal areas on your cervix and uses an instrument with a light and magnifier (called a colposcope) to make the abnormal areas easier to see. Your doctor or nurse might use a small amount of vinegar on your cervix to make any abnormal areas stand out.
If there is an abnormal area on the cervix, your doctor or nurse will perform a biopsy (remove a sample of tissue from your cervix) to check for cancer cells. Results of these tests will help your doctor or nurse decide on the best treatment to recommend.
What causes “unclear” or “abnormal” Pap test results?
A Pap test could come back “unclear” or “abnormal” for many reasons. Most often, abnormal cell changes are caused by HPV. HPV is an STI that can lead to cervical cancer.
Other reasons you may have Pap test results that are “unclear” or “abnormal” include:6
- An infection, such as a yeast infection, or inflammation
- Growths or cysts that are benign (not cancerous)
- Changes in hormones, such as during pregnancy or menopause
- Smoking, which may increase the risk of an HPV infection developing into cervical cancer. Get tips for women about quitting smoking .
- Problems with your immune system caused by certain medicines or health problems, such as diabetes, cancer, HIV, or autoimmune diseases
Do Pap tests have risks?
Yes. Although Pap tests are very safe, they do have limits.
- The Pap test may not find abnormal cells that are actually there. This means your doctor may tell you your cervical cells are normal, but the test missed a problem with the cells. This can delay the discovery and treatment of abnormal cells of the cervix. But having regular Pap tests increases your chances of finding problems. Cervical cancer usually takes many years — on average 10 to 20 years — to develop.7 If a Pap test misses abnormal cells, your doctor or nurse will probably find them on your next Pap test. Therefore, it is important to have Pap tests on the recommended schedule for your age and medical history.
- The Pap test results may report abnormal cells that are not really there. This means your doctor may tell you that your cervical cells are abnormal, but they are actually normal. There is no way to know that the cells are normal without further testing. Therefore, your doctor may do another Pap test or a different test to find out more. If the next Pap test or other test comes back normal, you don’t have to do anything until your next Pap test is scheduled.
What do my HPV test results mean?
Your HPV test results will show whether you have HPV and what type of HPV it is. Researchers know of about a dozen types of HPV, out of more than 200, that can cause cervical cancer.8
HPV test results are usually given with Pap test results. Having the two tests together (called co-testing) can help your doctor figure out if you need to be tested more often or need different tests.
If you do not have HPV and your Pap test results are normal, you can probably wait to be tested again for 5 years.
Can a Pap test tell me whether I have a sexually transmitted infection (STI)?
No. A Pap test is not used to find STIs. A Pap test is used to find abnormal cells that may cause cervical cancer. You must ask your doctor to test you for STIs if you want to have STI testing.
If you tell your doctor you would like to be tested for other STIs, your doctor can collect samples of fluid from your cervix to test for common STIs, such as chlamydia and gonorrhea. You will need blood tests to test for other STIs.
How can I lower my chances of getting cervical cancer?
You can lower your chances of getting cervical cancer in several ways:
- Get regular Pap tests. Regular Pap tests help your doctor find cell changes and treat any unhealthy cells before they turn into cancer.
- Get regular Pap and HPV tests together or an HPV test alone (if you are between 30 and 65 years old). Doctors recommend getting an HPV test or co-testing (getting a Pap and HPV test together) for most women between 30 and 65.
- Get an HPV vaccine (if you are 26 or younger). Cervical cancer is usually caused by types of HPV that are passed from person to person through genital contact. Most women do not have symptoms of HPV, and HPV sometimes goes away on its own. If HPV does not go away on its own, it can cause changes in the cells of the cervix that can lead to cervical cancer. The HPV vaccine prevents you from getting most cancer-causing types of HPV.
- Take steps to lower your risk. If you have sex, lower your risk of getting HPV with the following steps:
- Use condoms. Condoms are the best way to prevent STIs when you have sex. HPV can happen in female and male genital areas that are not protected by condoms. But research shows that condom use is linked to lower cervical cancer rates.9,10 Also, the HPV vaccine does not replace or decrease the need to wear condoms. Make sure to put the condom on before the penis touches the vagina, mouth, or anus. Other methods of birth control, like birth control pills, shots, implants, or diaphragms, will not protect you from HPV or other STIs.
- Get tested. Be sure you and your partner are tested for STIs. Talk to each other about the test results before you have sex.
- Be monogamous. Having sex with only one partner can lower your risk of STIs. After being tested for STIs, be faithful to each other. That means that you have sex only with each other and no one else.
- Limit your number of sex partners. Your risk of getting STIs goes up with the number of sexual partners you have.
- Do not douche. Douching removes some of the normal bacteria in the vagina that protect you from infection. This may increase your risk of getting STIs.
- Be aware of how much alcohol you drink and keep control of your own drink. Some people use alcohol or drugs as a way to make a person drunk or high. Someone who is drunk, drugged, or high on drugs is unable to consent or understand what is happening. This puts you at risk of sexual assault and possible exposure to STIs.
These steps work best when used together. No single step can protect you from HPV.
