Pap Smear in Chennai: When to Book It, What to Avoid Beforehand, and What Happens in the Room

India's national programme screens women aged 30 to 65 for cervical cancer, once in five years (MoHFW, Operational Framework: Management of Common Cancers, 2016). ICMR-NICPR advises a Pap test every three years from age 30, or every five years if it is combined with an HPV test. The test is done while you feel completely well. There is nothing to feel, and that is the entire point of booking it.

This article is written for a woman in Chennai who has either never had a Pap smear or is putting one off, and who wants to know what the few minutes actually involve before she agrees to them. It covers who is screened and how often in India, what to avoid in the days before the test and why, what is done in the room, and what an abnormal result does and does not mean.

One thing before the rest of it, because it is the situation this article does not cover. AJSMC is an outpatient and day-care multi-specialty centre in Chennai, open Monday to Saturday, 10am to 9pm. It has no casualty unit, no emergency department, no inpatient beds and no intensive care. Heavy vaginal bleeding — soaking through a pad an hour — fainting, or severe pelvic pain is not a screening problem and must not wait for an outpatient appointment. Call 108 or go to the nearest hospital with a 24-hour emergency department. Outside our hours, and all day Sunday, there is no outpatient service here at all.

Who should have a Pap smear, and from what age in India?

Women from age 30 to 65, under every Indian source. India's public programme starts at 30, uses visual inspection with acetic acid (VIA) as its population test, and repeats it once in five years (MoHFW, 2016). It does not screen women aged 21 to 29 at all, and it does not use cytology as the population test. That is a real difference from the American guidance most search results return, and it is worth knowing which one you are reading.

Two things follow from that table for a woman in Chennai. The shortest interval any guideline anywhere recommends is three years, so an annual Pap smear is not supported by any of them — if you are being offered one every year, ask which guideline it comes from. And patient-collected sampling, which USPSTF endorsed for the United States in 2025 at the same five-year interval it sets for clinician collection, is not what India's public programme runs; screening here is performed by a clinician.

The condition being screened for is not rare. WHO's cervical cancer fact sheet records around 604,000 new cases and around 280,000 deaths worldwide in 2024.

Why does screening start at 30 in India when the US starts at 21?

Because of how slowly the disease develops, and because a screening programme is designed around the population it serves. WHO states that it usually takes 15 to 20 years for abnormal cervical cells to become cancer, and 5 to 10 years in women with weakened immune systems such as untreated HIV. That long interval is what makes screening work at all: there is a decade or more in which a precancerous change can be found and dealt with.

It also explains why screening at 30 is not "late". A test at 30, repeated on schedule, sits well inside that window. India's programme, WHO's guideline and the US guidance all target the same biology and differ mainly in what test the health system can deliver at scale (MoHFW 2016; WHO 2021; USPSTF 2025).

Does a Pap smear test for cancer?

No, and it is a common misunderstanding. A Pap smear looks for precancerous changes in the cervical cells; HPV infection is looked for by a separate HPV test, which may or may not be requested alongside it. Those cell changes are present long before there is anything to feel, see or complain about, and the whole design of screening is that it is done in the absence of symptoms.

Most of what it finds resolves on its own. WHO's HPV fact sheet states that in 90% of people the body controls the infection by itself. NCI's PDQ summary records that about 70% of ASC-US and CIN 1 lesions regress within six years, that about 6% of CIN 1 lesions progress to CIN 3 or worse, and that in about 10 to 20% of women with CIN 3 lesions those lesions progress to invasive cancer.

Read that table as the reason screening targets precancer rather than cancer. Almost everything found on a screening test is a change that will either go away by itself or can be dealt with at a stage where dealing with it is straightforward.

What should you avoid in the days before a Pap smear?

Anything that washes away or obscures the cervical cells the laboratory needs to read. That is the reason the sources give, and it is worth stating plainly, because the avoid-list is often mistaken for modesty rules. It is not about propriety. It is about whether there are enough readable cells on the slide.

The seven-day window is the one most women miss, because it is far longer than the two days people tend to assume, and it covers ordinary lubricants and moisturisers as well as medicines. Plan the appointment around it rather than the other way round.

On timing within the cycle, the American Cancer Society says the best time is at least five days after your period stops. If you are bleeding on the day of the appointment, call on 044 2532 2021 and ask whether to keep it or move it rather than deciding either way on your own. And if you did have intercourse the night before after all, keep the appointment and tell the doctor rather than silently cancelling.

What actually happens in the room, and how long does it take?

It is done as part of a pelvic examination and lasts only a few minutes (NCI, Cervical Cancer Screening patient page). The sequence is short and there is nothing hidden in it:

1. You lie on your back, bend your knees, and place your feet in supports.
2. The doctor uses a speculum to gently open the vagina so the cervix can be seen.
3. A soft, narrow brush or a small spatula is used to collect a sample of cells from the cervix. The American Cancer Society describes cells being taken from two areas, the outer surface of the cervix and the opening of the cervical canal.
4. The sample goes to a laboratory, where it is examined for abnormal cells and, depending on what has been requested, tested for HPV.

Nothing is cut and nothing is removed apart from surface cells. If any part of the examination hurts, say so while it is happening rather than afterwards, the examination can be paused or stopped. If you would like a second person present in the room, ask when you book, on 044 2532 2021.

On the report: NCI's patient page tells American readers that results come back in about one to three weeks. Treat that as a United States figure and not as a commitment by any Indian laboratory. Before travelling for the test, call AJSMC on 044 2532 2021 and ask which of the tests named in this article are run in-house in Chennai, which are sent to a referral laboratory, and how the result will reach you.

One result that unsettles people unnecessarily is a request to repeat the test because the sample could not be read. Given that intercourse, douching, creams, foams and menstrual blood all interfere with the cells reaching the slide, a laboratory that cannot read a sample is reporting a problem with the sample, not a finding about your body. It is a repeat, not a result.

Which test is best — Pap, VIA or HPV?

The largest Indian trial ever run on this question answers it, and the answer is HPV testing. In Osmanabad district, 131,746 women aged 30 to 59 across 52 clusters were randomised to a single round of HPV testing, cytology, VIA, or standard care (Sankaranarayanan R et al., New England Journal of Medicine, 2009).

A single round of HPV testing significantly reduced both advanced cancers and deaths. Neither cytology nor VIA reached statistical significance over one round. That is why WHO's 2021 guideline puts HPV DNA detection first and why FOGSI's 2018 recommendations name HPV testing as the preferred method where resources allow, with VIA by trained providers as the option suited to low-resource settings until an affordable HPV test is available.

None of this means a Pap smear is not worth having. It means the test you are offered should be a deliberate choice made with the gynaecologist, and that a single Pap is a less sensitive instrument than the number of women who have had one might suggest, which is another reason the guidelines set an interval and expect it to be kept.

How many women in Chennai have actually been screened?

Very few, and this is the number that puts an individual decision in context. Under NFHS-5 (2019–21), 1.9% of Indian women aged 30 to 49 had ever undergone a cervical cancer screening test. A community-based cross-sectional survey of 4,184 women aged 30 to 69 across Tamil Nadu found that 423 of them — 10%, with a 95% confidence interval of 9 to 12% — reported ever having been screened (Scientific Reports, 2026).

With nine women in ten never screened even at the state figure, the first test, not the repeat, is the one most women in Chennai still need to book.

What does an abnormal result mean?

Usually an early cell change, not cancer. NCI states it directly in its patient guide: most abnormal cervical screening results are not cervical cancer, but early cervical cell changes that can be monitored or treated. Results are reported using the Bethesda System, whose categories include ASC-US, AGC, LSIL, ASC-H, HSIL, AIS and cervical cancer, most reports land at the mild end of that list.

The US denominators, which are the ones large enough to quote, show how routine a callback is. Of roughly 65 million screenings a year in the United States, about 6% — 3.9 million women — are asked to come back for further evaluation (NCI PDQ). A positive HPV test is even less predictive on its own: 86.7% of women with a positive HPV test did not develop cervical cancer or related premalignant disease after more than a decade. With co-testing, 11% of women aged 30 to 34 have normal cytology alongside a positive HPV test, falling to 2.6% by ages 60 to 65.

NCI's own framing of the trade-off is worth carrying: to prevent one cervical cancer death, more than 150 women have an abnormal result, more than 80 are referred for investigation, and more than 50 have treatment. Screening works by casting wide and following up carefully. A positive screen is a reason for the next test, not a diagnosis, and being asked back is the system doing what it is designed to do.

What happens after an abnormal result?

Usually colposcopy. A speculum is inserted as for the smear, and the cervix is examined through a colposcope, a magnifying instrument that stays outside the body. Dilute acetic acid is applied, and abnormal squamous epithelium turns white. That "acetowhite" change tells the doctor where to take a biopsy, and the biopsy is what gives a definitive diagnosis. If nothing abnormal is seen, no treatment is needed (NHS colposcopy patient information; ASCCP Colposcopy Standards).

In India's public system, that pathway runs through the district hospital, which the MoHFW framework expects to be able to offer colposcopy and cryotherapy (MoHFW, 2016). Colposcopy, biopsy and the treatments that follow them are not services this article claims for AJSMC; ask on 044 2532 2021 where a referral for them would go before assuming any of it happens in one building.

Do you still need a Pap smear if you have had the HPV vaccine?

Yes. WHO states it in the plainest terms available: precancers rarely cause symptoms, which is why regular cervical cancer screening is important even if you have been vaccinated against HPV. USPSTF, the American Cancer Society and ASCCP all take the same position — screening recommendations do not change based on vaccination status.

The reason is in what the vaccine covers. India's national campaign uses Gardasil-4, which covers HPV types 16, 18, 6 and 11 (Press Information Bureau, 28 February 2026). It does not cover every high-risk HPV type, and screening looks for cell changes whichever type caused them. A girl vaccinated at 14 in 2026 enters the 30-to-65 screening window in 2042, and the screening interval applies to her exactly as it does to everyone else.

Source for that table: Press Information Bureau, Government of India, 28 February 2026. WHO's own position, separately, is that HPV vaccines should be given to all girls aged 9 to 14 years, before they become sexually active. That is the WHO age band, and it is wider than what India's current campaign delivers.

WHO's 90-70-90 elimination targets for 2030 tie the two halves together: 90% of girls fully vaccinated by 15, 70% of women screened with a high-performance test by 35 and again by 45, and 90% of women with precancer or cancer treated. Vaccination and screening are two of three targets, not alternatives to each other.

What if you already have symptoms?

Then this is no longer a screening question. ICMR-NICPR lists bleeding after intercourse, bleeding between periods, bleeding after menopause, and foul-smelling discharge among the symptoms of cervical cancer. Any of those should be assessed by a gynaecologist rather than answered with a routine screening appointment — screening is designed for women who have nothing to report.

And to repeat the line from the top of this article, because it is the one that matters most: heavy bleeding soaking a pad an hour, fainting, or severe pain is an emergency. AJSMC in Chennai has no emergency department, no inpatient beds and no intensive care, and is closed outside Monday to Saturday, 10am to 9pm, and all day Sunday. That situation goes to 108 or to the nearest hospital with a 24-hour emergency department, not to an outpatient booking.

When should you see a doctor?

If you are a woman aged 30 to 65 and have never been screened, book it. That is the recommendation of India's own national programme, and the Tamil Nadu figure of roughly one woman in ten ever screened is the gap it is trying to close. If you were screened and told to come back at a stated interval, keep that date even though nothing has changed in how you feel; nothing changing is the expected state.

See a gynaecologist sooner, and separately from any screening schedule, for bleeding after intercourse, bleeding between periods, bleeding after menopause, or foul-smelling discharge. If you have been vaccinated against HPV, keep screening on schedule anyway. If you are unsure which test you had last time or when it is due, take the old report with you rather than trying to remember it.

Outpatient consultations in Obstetrics and Gynaecology at AJSMC, Police Commissioner Office Road, Egmore, Chennai 600008, run Monday to Saturday, 10am to 9pm, on 044 2532 2021. Before you travel, ask on that number which of the tests named in this article are run in-house and which are sent to a referral laboratory, and if you can, plan the appointment for at least five days after your period stops.
