Cervical cancer remains one of the most common cancers and claims the lives of Thai women every day. The good news is that this type of cancer is preventable and curable if detected early. Since the causative virus takes many years to develop, we have a “golden window” to identify risks and stop this deadly disease before it’s too late.
What every woman must know is that “early-stage cervical cancer usually shows no abnormal symptoms.” Waiting for symptoms before seeing a doctor may be too late. Regular screening is therefore the most important tool to protect your life.
In-depth look at current screening technology
Currently, the global concept of cervical cancer screening, including in Thailand, has shifted from “detecting abnormal cells” to “detecting the causative virus at the source” to help identify risks before cells begin to change.
Dr. Wanchat Komol, Obstetrician-Gynecologist specializing in Female Pelvic Medicine and Reconstructive Surgery, Phyathai Hospital 2 explains that today, women’s health care focuses not only on detecting abnormalities after disease onset but also emphasizes risk assessment and disease prevention from the early stages to enable appropriate long-term health care planning.
To clarify, let’s compare the three popular cervical cancer screening methods today: Pap Smear, ThinPrep, and Primary HPV DNA Testing, to see how they differ and who they are suitable for.
Comparison table of cervical cancer screening methods
| Screening Method | What it detects | Highlights/Advantages | Screening Frequency* |
| Pap Smear | Detects early abnormal cells | Traditional method, widely used | Every 2 years |
| ThinPrep | Detects early abnormal cells using a solution technique that improves sample quality | Reduces interference in reading results | Every 2 years |
| Primary HPV DNA Testing (Currently recommended screening method) | Directly detects the cause at the DNA level of High-risk HPV (high-risk strains) | – Identifies risk from the source before cell changes occur
– Effective in detecting risk from early stages – Helps plan long-term follow-up well |
Every 5 years
(If results are normal, screening intervals can be extended) |
* Clinical practice guidelines of the Royal Thai College of Obstetricians and Gynecologists, 2025
In summary, Pap Smear and ThinPrep detect existing abnormal cervical cells, while Primary HPV DNA Testing focuses on identifying risk factors from HPV before cell changes occur.
Why do global and Thai trends emphasize HPV DNA Testing?
Because international research confirms that testing for high-risk HPV strains can assess risk faster and more accurately than cell examination alone. The Royal Thai College of Obstetricians and Gynecologists, together with the National Cancer Institute, has issued the latest guidelines supporting increased access to HPV-based screening for women.
Besides accuracy, “cost-effectiveness and peace of mind” are completely different. If you choose Primary HPV DNA Testing and the result is normal (Negative), you can extend the screening interval up to 5 years, avoiding the anxiety and frequent pelvic exams every 2 years as with traditional methods.
Who is Primary HPV DNA Testing suitable for?
Thai women aged 25 and above should start cervical cancer screening, especially those with the following risk factors:
- Those who want to plan proactive long-term health care with their doctor
- Those who have never undergone cervical cancer screening before
- Those with a history of HPV infection or previous abnormal cervical cell test results
FAQ Frequently Asked Questions about Cervical Cancer Screening
Q : Does HPV DNA Testing hurt?
A: It does not hurt. The procedure is similar to a general pelvic exam, takes only a few minutes, and you can immediately return to your daily activities or work.
Q : If the result is HPV Positive, does it mean I have cancer?
A: No. A positive result means “high-risk HPV strains are detected in the body,” but it does not mean cancer. Doctors will use this result to plan close monitoring or additional tests to prevent the virus from developing into cancer in the future.
Q : If I have been vaccinated against HPV, do I still need screening?
A: Yes, screening is still necessary because the vaccine protects well against the most common strains but does not cover all high-risk HPV strains. Combined screening is the safest approach.
Q : If I am under 25 years old, do I need screening?
A: According to international standards and the Royal College guidelines, if you are under 25 and have no abnormal symptoms, general screening is not recommended except for high-risk groups such as those with multiple sexual partners, immunocompromised conditions (HIV infection), or sexually transmitted infections like genital warts.
Q : Do women who have had a hysterectomy still need cervical cancer screening?
A: If the uterus and cervix were removed together (Total Hysterectomy) and there is no history of severe lesions (CIN 2-3, AIS) or cervical cancer, screening is no longer necessary.
Q : How should I prepare before the test?
A: Avoid sexual intercourse, vaginal douching, and using vaginal medications for at least 24-48 hours before the test. Also, avoid scheduling the test during menstruation to allow the doctor to collect the most complete and accurate cell samples.
