Definition (MEDLINEPLUS)

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
Definition (NCI) A non-neoplastic or neoplastic disorder that affects the cervix. Representative examples include cervicitis, endocervical polyp, and carcinoma.
Definition (CSP) deviation from or interruption of the normal structure or function of the cervix.
Definition (MSH) Pathological processes of the UTERINE CERVIX.
