A Pap smear (Pap test) is a quick check in which a doctor or nurse collects a few cells from the cervix, the narrow lower end of the womb, and sends them to a lab. It looks for cell changes that could turn into cervical cancer years later, so they can be treated early or watched.
The test takes only a few minutes and should not be painful, though it can feel odd. Below you will find how to prepare, what happens, how to read results and how screening advice differs between countries.
What a Pap smear and an HPV test check
Nearly all cervical cancers are linked to long-lasting infection with the human papillomavirus (HPV). WHO notes that two types, HPV 16 and 18, are behind about 76% of cases. Two tests are used for screening, and they look for different things:
- Pap test: checks the cervical cells for precancerous changes.
- HPV test: checks the same sample for the virus that can cause those changes.
Both use a sample taken from the cervix in the same way. Depending on the country and the doctor, you may be offered one test or both together (co-testing). Screening is for women with no symptoms. If you already have bleeding or pain, tell your doctor instead of waiting for a routine test.
Who should be tested, and how often?
Guidelines vary by country, so use these as examples and ask your own doctor what suits you.
- WHO: an HPV test every 5 to 10 years for women from age 30. For women living with HIV, every 3 to 5 years from age 25.
- CDC (United States): start Pap tests at 21; if normal, the next one can wait three years. From 30 to 65, options are an HPV test alone or HPV plus Pap every five years, or a Pap alone every three years.
- NHS (England): women aged 25 to 64 are invited every 5 years.
- India's public programme: aims to screen women aged 30 to 65, mainly with a visual inspection method called VIA at sub-health centres and primary health centres, with a referral for further tests if the result is positive.
The CDC says some women over 65 can stop if they have had enough normal results in the past 10 years and no history of precancer. Do not stop on your own; this decision should come from your doctor. Our guide to cervical cancer screening and the HPV vaccine covers the vaccine side.
How to prepare
For a Pap test, the CDC advises avoiding sex, douching, vaginal medicines and spermicidal foam for two days before. An HPV test needs no special preparation. A period does not stop the test from being done, though some clinics prefer to reschedule if bleeding is heavy, so it is fine to call ahead.
- Wear a skirt or loose dress you can keep on during the test.
- Note the date of your last period and any bleeding after sex.
- Tell the doctor if you are pregnant, may be pregnant or have had cervical treatment before.
- Bring a friend or family member if that helps you feel calm.
Tip: You are in control. The NHS reminds patients they can ask to stop at any time, and can ask for a smaller instrument or a different position, such as lying on your side, if the usual one is uncomfortable.
What happens during the test
- You undress from the waist down behind a screen and lie on the couch with your knees bent.
- The doctor gently places a smooth instrument called a speculum in the vagina to hold the walls apart and see the cervix.
- A soft brush or small spatula collects cells and mucus from the cervix.
- The speculum is removed and you get dressed.
The NHS says collecting the sample takes under 5 minutes and the whole visit about 10 minutes. You may notice light spotting afterwards that usually stops within a few hours. Heavy bleeding or spotting that continues needs a doctor's review.
Understanding your results
Results can take up to three weeks, according to the CDC. Most results are normal. Other results are common too and rarely mean cancer.
- Normal: no abnormal cells. You return at the advised interval.
- Unclear result: the cells look slightly unusual but the cause is not known. An HPV test may help to decide next steps.
- Abnormal result: usually linked to HPV. Minor changes often clear on their own, while more serious changes may need treatment to stop cancer from developing.
- HPV positive: you carry a high-risk HPV type. This does not mean you have cancer now. Your doctor may arrange a closer look.
- Unsatisfactory sample: too few or clumped cells, so the test is usually repeated in a few months.
If more checking is needed, a doctor may do a colposcopy, which is a magnified look at the cervix. Follow-up visits matter more than the first result, so keep every appointment.
Myths and facts
- Myth: I had the HPV vaccine, so I do not need screening. Fact: WHO says vaccinated women still need screening because precancer rarely causes symptoms.
- Myth: A positive HPV test means cancer. Fact: It means the virus is present; most infections do not become cancer.
- Myth: Only women with many partners need tests. Fact: HPV is common, and screening is advised for every woman in the eligible age group.
- Myth: Screening is only needed when something hurts. Fact: Early changes usually cause no symptoms.
When to see a doctor
Book a visit without waiting for your next scheduled screening if you notice any of these, which WHO lists as symptoms to report:
- Bleeding between periods, after sex or after menopause
- Increased or foul-smelling vaginal discharge
- Pain in the pelvis, back or legs that does not go away
- Unexplained weight loss, tiredness or loss of appetite
When to be cautious: These symptoms often have simple causes such as infection, but they should always be checked. Please do not delay because the result might be frightening; early checking gives the most treatment choices.
What to expect at the clinic
A doctor will usually ask about your periods, pregnancies, previous screening and any symptoms before the test. Our reproductive care team and general gynaecology doctors can explain which test suits your age. If you are pregnant or planning a pregnancy, mention it, since screening is often combined with your regular gynaecological checkup.
