The main function of a Pap smear is to detect abnormal cervical cells before they develop into cancer. Regular screening allows for early intervention, when treatment has better outcomes.
Pap Smear in Singapore
A Pap smear is a screening test used to detect cervical cancer and early cellular changes that may lead to it. The test involves collecting a sample of cells from the cervix—the lower part of the uterus that opens into the vagina. A speculum is gently inserted during the procedure to allow your doctor to view the cervix. A small brush or spatula is then used to collect the cell sample, which is examined under a microscope for abnormalities. Regular Pap smears help identify changes early, when they are most treatable.

When Pap Smears Are Recommended
Pap smears may be performed for several reasons related to women’s health. These include:
Cervical Cancer Screening
HPV Detection
Many Pap tests are now combined with HPV testing to identify the presence of high-risk human papillomavirus strains that can lead to cervical cancer. This combined approach provides more comprehensive screening.
Monitoring After Abnormal Results
Women who have previously had abnormal Pap results may require more frequent testing to monitor cellular changes and determine whether further intervention is needed.
Post-treatment Surveillance
Following treatment for cervical abnormalities, Pap smears help monitor the cervix to confirm treatment effectiveness and detect any recurrence.
Benefits of Pap Smears
Pap smears provide several advantages for women’s health. These include:
-
Early Detection
Pap smears can detect precancerous changes years before cervical cancer develops, allowing for intervention at stages when treatment is less complex and often more effective.
-
Reduced Cancer Rates
Regular Pap screening has led to fewer cervical cancer cases by enabling early detection and treatment.
-
Quick Procedure
The test is brief, can be performed during a routine gynaecological examination, and requires no recovery time.
-
Preventive Healthcare
As a preventive measure, Pap smears help avoid the need for more extensive treatment that may be required for advanced cervical cancer.
Preparing for a Pap Smear
Timing
Schedule your Pap smear when you are not menstruating. The most suitable time is the middle of your menstrual cycle, typically 10-20 days after the first day of your last period. Menstrual blood can affect the collection of cervical cells.
Avoidance of Certain Products
Refrain from using vaginal medications, spermicides, lubricants, or douches for at least 48 hours before your appointment. These products can wash away or obscure cervical cells, affecting test results.
Sexual Activity
Avoid sexual intercourse for 24-48 hours before your test. Semen and vaginal lubricants can interfere with the collection of cells and test interpretation.
The Pap Smear Procedure
Consultation
The procedure begins with an explanation and an opportunity to ask questions. visit, or your records will be updated as needed.
Positioning
You will lie on your back on an examination table with your knees bent and feet placed in stirrups. A sheet will cover your lower body for privacy, with only the necessary area exposed for the examination.
Speculum Insertion
A speculum, a device that holds the vaginal walls apart, is inserted to allow visualisation of the cervix. The speculum may feel cool and create a pressure sensation but should not cause significant pain.
Cell Collection
Cell samples are collected from the cervix and surrounding area using a small brush or spatula. This collection takes only a few seconds and may cause mild discomfort, such as a brief pinching or cramping sensation.
Sample Preparation
The collected cells are either spread onto a glass slide (conventional method) or placed in a liquid preservative (liquid-based cytology) for transportation to the laboratory for examination.
Post-Procedure Care
-
Light Spotting
Some women experience light spotting after a Pap smear. The spotting should be minimal and resolve within a day.
-
Activity Resumption
Most women can resume normal activities right away, including work and exercise. There is no recovery period needed after a Pap smear.
-
Result Notification
Results typically take 1-3 weeks to process. Your doctor will contact you with the results and any follow-up recommendations.
-
Follow-up Planning
If your results are normal, you will be advised when to schedule your next routine Pap smear. Your doctor will recommend appropriate follow-up tests or procedures if abnormalities are detected.

Potential Risks and Complications
Pap smears are generally procedures with minimal risks. Some women may experience brief discomfort during the speculum insertion or cell collection. Light spotting immediately after the procedure can occur, but typically resolves quickly. In rare cases, women with certain conditions, such as vaginal infections, may experience more discomfort. False negatives can happen where abnormal cells are present but not detected, which is why regular screening according to recommended guidelines is advised. False positives are also possible, leading to unnecessary worry and additional testing, though subsequent examinations typically clarify results.
Frequently Asked Questions (FAQ)
How often should I get a Pap smear?
Your doctor may recommend Pap smear screening every 3 years for women aged 21-29. For women 30-65, screening options include a Pap test every 3 years, HPV testing every 5 years, or co-testing (Pap plus HPV) every 5 years. Different testing intervals may be recommended based on your health history.
Should I get a Pap smear if I’ve had a hysterectomy?
If you’ve had a total hysterectomy (including removal of the cervix) for non-cancerous conditions, you generally don’t need Pap smears. However, if your hysterectomy was due to cancer or precancerous conditions, or if you still have your cervix, continued screening may be recommended.
Will a Pap smear detect all gynaecological cancers?
A Pap smear specifically screens for cervical cancer and precancerous changes. It does not detect ovarian, uterine, vaginal, or vulvar cancers. Regular gynaecological examinations and awareness of symptoms remain valuable for overall reproductive health.
