Cervical dysplasia is when there are abnormal, or precancerous, cells in and around a woman’s cervix. Cervical dysplasia is detected by a pap test (pap smear). It is diagnosed with a biopsy. Abnormal changes in cells can be mild, moderate, or severe. The presence of cervical dysplasia does not mean you have cervical cancer, but the cells could lead to cancer if they are not treated. Women with cervical dysplasia do not usually have any symptoms. Therefore, it’s important to get screened regularly.
