Cervical cancer begins in the cervix, the opening between the vagina and uterus. Most cases are caused by human papillomavirus (HPV). HPV is a virus, not a type of cervical cancer. Persistent infection with certain high-risk HPV types can cause changes in cervical cells that may develop into cancer. Most people with HPV do not develop cervical cancer.
Vaccination and regular screening offer important opportunities to prevent disease. Screening can identify changes before cancer develops, even when you feel well. If you have been diagnosed, understanding the cell type and extent of your cancer helps you prepare for treatment discussions.
