The cervix is the lower part of the uterus, the place where a baby grows during pregnancy. The cervix has a small opening that expands during childbirth. It also allows menstrual blood to leave a woman's body.
Your healthcare provider may perform a Pap test during your
health checkup to look for changes to the cells of the cervix, including
cervical cancer. Other problems with the cervix include:
-
Cervicitis: inflammation of the cervix
-
Cervical incompetence: widening of the cervical opening during pregnancy long before the baby is due
-
Cervical polyps and cysts: abnormal growths on the cervix
