How does multiple pregnancy occur? A pregnancy with more than one fetus is called multiple pregnancy. If more than one egg is released during the menstrual cycle and each is fertilized by a sperm, more than one embryo may implant and grow in your uterus. This type of pregnancy results in fraternal twins (or more). When a single fertilized egg splits, it results in multiple identical embryos. This type of pregnancy results in identical twins (or more). Identical twins are less common than fraternal twins.

What is cancer of the cervix? A woman’s cervix (the opening of the uterus at the top of the vagina) is covered by a thin layer of tissue made up of cells. Healthy cells grow, divide, and are replaced as needed. Cancer of the cervix occurs when these cells change. Cancer cells divide more rapidly. They may grow into deeper cell layers or spread to other organs. The cancer cells eventually form a mass of tissue called a tumor.
