Pap test: a key test for early detection of cervical cancer
What is a Pap test?
The Pap test, or Papanicolaou smear, is a cytological examination of cervical cells that detects precancerous changes or early stages of cancer. It is named after the Greek physician Georgios Papanicolaou, who developed the method in the 1940s.
The test is one of the most effective cervical cancer screening tools, recommended by the WHO and national health programs in many countries.
Who needs a Pap test and when?
It is recommended to undergo a Pap test:
women aged from 21 to 65 years old
every 3 years (or every 5 years if combined with HPV test)
regardless of symptoms or sexual activity (except for those under 21 years of age)
The test is especially important for women who have:
early onset of sexual activity
multiple sexual partners
smoking or immunodeficiency states
history of HPV or cervical dysplasia
How the procedure works
A Pap test is a quick and painless procedure:
A doctor or nurse takes a swab from the cervix using a special brush or spatula.
The sample is placed on glass or in a liquid medium (liquid cytology).
The sample is sent to a laboratory for cell analysis.
The procedure lasts no more than 5 minutes, does not require anesthesia and is performed on an outpatient basis.
How to prepare for a Pap test
To make the result as accurate as possible:
do not take the test during menstruation
abstain from sex 24 hours before the procedure
do not use vaginal creams, pills, suppositories
do not douche 2 days before the test
These factors can change the cellular structure or wash away the cells that need to be examined.
What does a Pap test show?
Pap test results can be:
Norm (NILM) – cells without pathologies
ASC-US – atypical cells of unclear significance
LSIL/HSIL – mild or severe abnormalities that may indicate dysplasia
AGC – atypical glandular epithelial cells
Suspicion of cancer – requires urgent further examination
If abnormalities are detected, additional tests may be recommended: colposcopy, biopsy, or HPV test.
Benefits of the Pap test
Early detection of precancerous changes
Reduction in cervical cancer mortality by 70–80%
Easy to implement and highly informative
Possibility of combining with HPV test to increase accuracy
Limitations of the method
Does not detect all types of cancer (e.g. endometrial)
Possible false positive or false negative results
Requires regularity: a one-time test is not a guarantee of safety
Modern variations: liquid cytology and Pap test + HPV
Newer techniques, such as liquid-based cytology, provide higher accuracy and reduce the number of false positives. Combined Pap + HPV testing detects not only cell changes, but also the human papillomavirus itself, which is the main cause of 99% cases of cervical cancer.
Thanks to these methods, modern prevention of gynecological diseases has reached a new level - an effective, affordable, and personalized approach to women's health.
Pap test — is more than an analysis. It is a simple but powerful tool that gives women a chance to learn about the threat in time and take action. Timely testing saves lives.
