Cervical Neoplasia

cervical neoplasia
Cervical intraepithelial neoplasia (CIN), also known as cervical dysplasia, is the abnormal growth of cells on the surface of the cervix that could potentially lead to cervical cancer. [1] More specifically, CIN refers to the potentially premalignant transformation of cells of the cervix. Cervical intraepithelial neoplasia most commonly occurs at the squamo-columnar junction (SCJ) of the cervix, referring to a transitional area between squamous epithelium of the vagina and the columnar epithelium of the endocervix but can also occur in vaginal walls and vulvar epithelium. CIN is graded on a 1-3 scale, 1 being less abnormal than 3 (see classification section below).
