What is Cervical Cancer?

Cervical cancer begins in the cells lining the cervix, the lower part of the uterus connecting to the vagina. It is most often caused by persistent infection with high-risk types of human papillomavirus (HPV). Key facts: it is one of the most preventable cancers through HPV vaccination and regular screening, yet remains a leading cause of cancer death in women worldwide. Early-stage cervical cancer often has no symptoms, highlighting the importance of routine Pap smears and HPV testing.
