Cervix Disorders

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 health care 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. This is usually from an infection.
  • Cervical incompetence - This can happen during pregnancy. The opening of the cervix widens long before the baby is due.
  • Cervical polyps and cysts - abnormal growths on the cervix
