Cervical Cancer Screening, Pap Smear and HPV Vaccination
Cervical cancer is one of the most common cancers affecting women in India, and it is also one of the most preventable. It develops slowly, over years, from changes in the cells of the cervix that cause no symptoms at all while they are still easy to treat. Screening exists to find those changes during that silent window.
That is the part worth holding on to. A screening test is not looking for cancer. It is looking for changes that might one day become cancer if nobody looks. Sai Speciality Center provides cervical screening and HPV vaccination in Kasturi Nagar, Bengaluru.
Why Screening Works
Almost all cervical cancer is caused by long-lasting infection with certain high-risk types of human papillomavirus, or HPV. HPV infection is extremely common and in most people clears on its own without ever causing a problem. In a minority it persists, and over years it can cause cell changes that progress.
Because that progression is slow, regular screening catches the great majority of cases at a stage where treatment is straightforward and the cervix can usually be preserved.
The Tests
Pap smear
A small sample of cells is gently taken from the cervix with a soft brush during an internal examination. It takes a couple of minutes. Most women describe it as briefly uncomfortable rather than painful, and some spotting afterwards is normal.
The sample is taken at the clinic and examined for abnormal cells. You will be told when to expect the result and how you will receive it.
HPV test
Taken the same way, but testing for the virus itself rather than for cell changes. Because it identifies risk earlier, a negative HPV test is reassuring for longer than a negative Pap smear, which is why screening intervals are longer when HPV testing is used. The two tests are sometimes done together on the same sample.
When to start and how often
Recommendations vary between guidelines, and the right interval for you depends on your age, your previous results and your medical history. As a general shape, screening begins in your twenties and is repeated every few years while results stay normal, and more often if a previous result was abnormal.
What matters more than the exact interval is not letting it drift for a decade, which is what usually happens. Your doctor will tell you when to come back, and that date belongs in your calendar.
What an Abnormal Result Means
An abnormal screening result is common and is not a diagnosis of cancer. In most cases it reflects minor cell changes that resolve on their own, and the next step is simply a repeat test after an interval.
Where changes are more significant, the usual next step is colposcopy, a closer examination of the cervix using a magnifying instrument, with a small biopsy if needed. Biopsies are taken at the clinic. Colposcopy is carried out at Rainbow Hospitals, HRBR Layout, where Dr. Kavitha is a senior consultant, so the person examining you is the person who has been looking after you.
If treatment is required it is usually a short day procedure that removes the affected area of the cervix, and it is highly effective at that stage. If you have been told a result was abnormal and have not followed it up, that is worth doing now rather than at your next routine visit.
HPV Vaccination
Vaccination protects against the high-risk HPV types responsible for most cervical cancer. It works best when given before any exposure to the virus, which is why it is recommended in early adolescence, typically from around nine years of age. Fewer doses are needed when the course is started young.
Vaccination is also available to older adolescents and adults, with more doses required. It offers less benefit after exposure has already occurred, but it is not pointless, and whether it is worthwhile for you is a reasonable thing to ask at a consultation. Both Indian-made and imported vaccines are available.
The HPV vaccine is stocked and given at the clinic, so vaccination and screening can be arranged in the same place rather than sending you elsewhere for one of them.
One point is often misunderstood and matters a great deal. Vaccination does not replace screening. The vaccine covers most high-risk HPV types but not all of them, so vaccinated women still need to be screened on the same schedule.
Symptoms That Should Not Wait for a Screening Appointment
Screening is for women without symptoms. If any of the following are happening, book an appointment rather than waiting for a routine test.
- Bleeding between periods, or after intercourse
- Any bleeding after menopause
- Persistent unusual vaginal discharge, particularly if it is blood-stained or offensive
- Persistent pelvic pain, or pain during intercourse
These symptoms have many causes, most of them not cancer. See general gynaecology for what else can produce them. But they need assessment rather than a screening test, because a screening test is not designed to answer that question.
Screening, Vaccination and What Each One Does
| What it is | What it does | Who it is for |
|---|---|---|
| HPV vaccination | Prevents infection with most high-risk HPV types | Best from around age nine, before exposure |
| Pap smear | Finds cell changes that have already started | Women from their twenties, every few years |
| HPV test | Finds the virus before cell changes appear | Often from age thirty, at longer intervals |
| Colposcopy | Examines the cervix closely after an abnormal result | Only when screening indicates it |
What to Expect at the Appointment
Try to book when you are not bleeding, since blood can obscure the sample. Mid-cycle is usually ideal. Avoid vaginal medicines or douching for a couple of days beforehand, and in any case douching is worth avoiding generally.
The examination is done privately by a woman doctor. It is brief. If you have found the examination painful or distressing in the past, say so at the start, because there are usually ways to make it easier.
You will be told when results are expected and how you will receive them, including what happens if they are normal, so that silence never has to be interpreted.
Frequently Asked Questions
Is a Pap smear painful?
It is usually brief and uncomfortable rather than painful, and takes a couple of minutes. Mild spotting afterwards is normal. If previous examinations have been painful, tell the doctor beforehand.
At what age should cervical screening start?
Screening generally begins in your twenties and continues every few years while results are normal. The right starting point and interval for you depends on your age, history and previous results, and your doctor will advise.
I have had the HPV vaccine. Do I still need screening?
Yes. The vaccine protects against most high-risk HPV types but not all of them, so vaccinated women follow the same screening schedule.
Does an abnormal Pap smear mean I have cancer?
No. Abnormal results are common and usually reflect minor cell changes that resolve on their own. Depending on the finding, the next step is either a repeat test after an interval or a colposcopy for a closer look.
Can I have a Pap smear during my period?
It is better to avoid it, because blood can obscure the sample. Mid-cycle is usually the best time to book.
Is HPV a sexually transmitted infection?
HPV is passed on through skin-to-skin genital contact and is very common. Most infections clear on their own without causing any problem. Having HPV does not imply anything about a partner, and it is not a reason to delay screening out of embarrassment.
Do I need cervical screening after a hysterectomy?
It depends on why the hysterectomy was done and whether the cervix was removed. Bring your operation details to the consultation and your doctor will tell you. See hysterectomy surgery for related information.
