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.
