Can HPV infection cause cervical cancer?

Most HPV infections are controlled by the immune system and do not lead to cancer. The concern is an infection that remains in cervical cells and gradually produces abnormal changes.

HPV is a group of viruses spread through close skin-to-skin sexual contact. Some types are described as high risk because persistent infection can interfere with the normal controls on cervical-cell growth. The resulting precancerous changes can sometimes progress if they are not found and managed.

An HPV result is not a cancer diagnosis. Cervical screening looks for high-risk HPV, abnormal cells or both, depending on the programme used. A clinician may recommend repeating a test or examining the cervix more closely with colposcopy when a result needs follow-up.

Attend cervical screening when invited and complete any recommended follow-up after an abnormal result. Screening can identify risk before cancer develops, when abnormal cells can be monitored or treated. The timing of repeat testing depends on the result, your age, previous findings and local clinical guidance.

HPV vaccination helps protect against important cancer-associated HPV types, but it does not treat an infection that is already present. Vaccinated people should still follow the cervical-screening schedule offered to them. Barrier methods can lower HPV transmission but cannot prevent every exposure because uncovered skin can carry the virus.

Arrange a medical appointment for bleeding after sex, bleeding between periods, bleeding after menopause, unusual persistent vaginal discharge or continuing pelvic pain. These symptoms have several possible causes, but each deserves assessment rather than waiting for the next routine screening test.

Seek urgent care if vaginal bleeding is heavy, you feel faint, or severe pelvic pain develops. Urgency is based on the severity of the symptom, not on whether HPV has previously been detected.

You may want to ask what your HPV or cervical-cell result means, when the next test is due, whether colposcopy is recommended, and what treatment would involve if abnormal cells are found. If you have symptoms, ask whether you need a separate diagnostic examination rather than routine screening.
