<unk>  <unk> , also known as<unk>  dysplasia, is the abnormal growth of cells on the surface of the cervix that could potentially lead to<unk>  cancer. More specifically,<unk>  refers to the potentially precancerous transformation of cells of the cervix.<unk>  most commonly occurs at the squamocolumnar junction of the cervix, a transitional area between the squamous epithelium of the vagina and the columnar epithelium of the endocervix. It can also occur in vaginal walls and vulvar epithelium.<unk>  is graded on a 1-3 scale, with 3 being the most abnormal (see classification section below). Human papilloma virus (HPV) infection is necessary for the development of<unk> , but not all with this infection develop<unk>  cancer. Many women with HPV infection never develop<unk>  or<unk>  cancer. Typically, HPV resolves on its own. However, those with an HPV infection that lasts more than one or two years have a higher risk of developing a higher grade of<unk> . Like other intraepithelial neoplasias,<unk>  is not cancer and is usually curable. Most cases of<unk>  either remain stable or are eliminated by the person's immune system without need for intervention. However, a small percentage of cases progress to<unk>  cancer, typically<unk>  squamous cell carcinoma (SCC), if left untreated.
