Cervical cancer is a disease that can be very serious. However, it is a disease that you can help prevent. Cervical cancer occurs when normal cells in the cervix change into cancer cells. This normally takes several years to happen, but it can also happen in a very short period of time. The good news is that there are ways to help prevent cervical cancer. By getting regular Pap tests and pelvic exams, your health care provider can find and treat the changing cells before they turn into cancer.
