What is cervical cancer?

When cancer starts in the cervix, it is called cervical cancer. The cervix is the lower, narrow end of the uterus. Also known as the womb, the uterus is where a baby grows when a woman is pregnant. The cervix connects the upper part of the uterus to the vagina (the birth canal).

All women are at risk for cervical cancer, occurring most often in women over age 30.

The main cause of cervical cancer is human papillomavirus (HPV) a common virus that is passed from one person to another during sex. At least half of sexually active people will have HPV at some point in their lives, but few women will get cervical cancer.
