How do HPV vaccination and cervical screening help prevent cervical cancer?
Prevention combines HPV vaccination, appropriate screening, follow-up and treatment of precancerous changes. Vaccination does not treat an existing infection or remove the need for screening. Age, doses and screening intervals follow the programme used and personal health.

Vaccination before exposure offers most benefit
Many programmes prioritise younger ages before viral exposure. People who missed vaccination can discuss eligibility and likely benefit; one country’s age limits or dose schedule should not be applied to everyone.
Screening uses different tests
HPV testing or cervical cytology may be used according to age, guidance and history. An abnormal result does not automatically mean cancer, but needs appropriate follow-up. Reduced immunity and previous treatment affect the plan.
Symptoms need separate assessment
Bleeding after sex, between periods or after menopause needs review even before the next screening date. Avoiding smoking reduces risk factors. Condoms can reduce HPV transmission but do not provide complete protection.
