What is cervical dysplasia?

Cervical dysplasia is a precancerous condition in which abnormal cells grow on the surface of your cervix. The cervix is the opening to your uterus that’s attached to the top portion of your vagina. Another name for cervical dysplasia is cervical intraepithelial neoplasia, or CIN. “Intraepithelial” means that the abnormal cells are present on the surface (epithelial tissue) of your cervix and have not grown past that surface layer. The word “neoplasia” refers to the growth of abnormal cells.
