About Cervical Cancer

PrintE-mailPDF

The cervix is part of a woman's reproductive system. It's in the pelvis. The cervix is the lower, narrow part of the uterus (womb).

The cervix is a passageway:

  • The cervix connects the uterus to the vagina. During a menstrual period, blood flows from the uterus through the cervix into the vagina. The vagina leads to the outside of the body.
  • The cervix makes mucus. During sex, mucus helps sperm move from the vagina through the cervix into the uterus.
  • During pregnancy, the cervix is tightly closed to help keep the baby inside the uterus. During childbirth, the cervix opens to allow the baby to pass through the vagina.
