The Cervix

To understand cervical cancer, it helps to be familiar with the anatomy of the cervix and surrounding areas. The uterine cervix is the neck of the uterus (or womb). If you were to think of an upside-down pear as a rough model of the uterus, the cervix would correspond to the narrow part of the fruit as it tapers toward the stem. The uterus is hollow in order to accommodate a fetus after conception occurs. This cavity opens to the vagina through the cervical canal, through which the fetus leaves the womb to enter the birth canal (the vagina) during childbirth.
