A Pap smear checks cells from the cervix for abnormal changes, while an HPV test looks for high-risk types of human papillomavirus, the main cause of cervical cancer. Both tests can detect problems early, often years before cancer develops. Regular screening is one of the most effective ways to prevent cervical cancer.
What Is a Pap Smear?
A doctor gently collects cells from the cervix using a small brush or spatula. The cells are examined under a microscope for abnormal changes.
What Is an HPV Test?
It checks the same or a similar sample for high-risk HPV types linked to cervical cancer. HPV infection is common and often clears on its own, but persistent infection can cause cell changes.
When Should Screening Start?
Guidelines differ, but common recommendations include:
- Starting between 21 and 25 years
- Pap smear every three years in younger women
- HPV testing every five years from around 30
- Continuing until about 65 if previous results are normal
India's national programmes may also use visual inspection with acetic acid (VIA) in some settings.
How to Prepare
- Schedule when you are not on your period
- Avoid intercourse, douching or vaginal medicines for 48 hours before
- Wear comfortable clothing
What Happens During the Test?
- You lie on an examination table
- A speculum is gently inserted
- Cells are collected from the cervix
- It takes a few minutes and may cause mild discomfort
Understanding Results
- Normal: routine screening continues
- HPV positive with normal cells: repeat testing or further evaluation
- Abnormal cells: colposcopy to look closely at the cervix and take biopsies if needed
Most abnormal results are due to minor changes that can be monitored or treated simply.
Treatment of Pre-Cancerous Changes
- Monitoring if changes are mild
- Removal of abnormal tissue with procedures like LEEP or cryotherapy
Prevention
- HPV vaccination, ideally before sexual activity begins
- Regular screening even after vaccination
- Avoid smoking
Key Takeaways
- Pap and HPV tests prevent cervical cancer.
- Screening usually starts in the early twenties.
- HPV testing is often every five years after 30.
- Abnormal results need follow-up, not panic.
- HPV vaccination adds strong protection.
Final Thoughts
Cervical cancer is largely preventable with regular screening and vaccination. A few minutes every few years can protect your health. For gynecological cancer evaluation, you can consult Dr. Varadharajan, a surgical oncologist in Chennai.
