Cervical cancer is almost entirely preventable through HPV vaccination and regular smear tests. Korea has a national HPV vaccination programme and cervical screening is available across health facilities.
Cervical cancer develops in the cells of the cervix (the lower part of the uterus). Almost all cases are caused by persistent infection with certain high-risk strains of Human Papillomavirus (HPV), a sexually transmitted infection. Globally, cervical cancer is the 4th most common cancer in women, but is largely preventable through a combination of HPV vaccination and regular cervical screening.
HPV vaccination: Korea offers HPV vaccination as part of its National Immunization Program, typically to girls aged 12, with the vaccine also increasingly offered to boys. The vaccine is highly effective (>90%) at preventing infection with the HPV strains that cause 70–90% of cervical cancers. It is most effective when given before sexual debut. Catch-up vaccination is recommended for those who missed the routine age.
Cervical screening (Pap smear / HPV test): The standard screening test involves collecting cells from the cervix to check for abnormal changes or HPV infection. Korea's National Cancer Screening Programme, run through NHIS, recommends biennial (every 2 years) Pap smear screening for women aged 20 and above, at minimal or no cost. Private clinics widely offer HPV co-testing.
Most screen-detected abnormalities (cervical intraepithelial neoplasia, CIN) are pre-cancerous changes that can be treated before cancer develops. Treatment is usually a simple colposcopy-guided procedure.
Key Points
- HPV causes 99% of cervical cancer — vaccination prevents the most dangerous strains
- Korea includes HPV vaccination in the National Immunization Program, offered to girls (and increasingly boys) around age 12
- NHIS's National Cancer Screening Programme offers biennial Pap smears from age 20
- Pre-cancerous changes detected by smear can be treated before cancer develops
- Vaccination is most effective before sexual debut but beneficial as catch-up too
- Do not skip screening even if you are vaccinated — vaccines do not cover all strains
Causes & Risk Factors
- Persistent infection with high-risk HPV strains (particularly HPV 16 and 18)
- Multiple sexual partners — increases HPV exposure
- Smoking — impairs cervical immunity
- Immunosuppression (HIV, organ transplant)
- Long-term oral contraceptive use (small increase in risk)
When to See a Doctor
- Due for routine cervical screening and not yet booked
- Unexpected vaginal bleeding — between periods, after sex, or post-menopause
- Unusual vaginal discharge
- Pelvic pain
- If you have not been vaccinated against HPV and are unsure of your status
