Living with Cervical intraepithelial neoplasia

A change in cells on the surface of the cervix that is not cancer but can become cancer if untreated.

Understanding Cervical intraepithelial neoplasia

Cervical intraepithelial neoplasia (CIN) is a precancerous condition in which cells lining the surface of the cervix look abnormal (dysplasia).

It is graded CIN 1, 2, and 3. CIN 1 is mild and is mostly watched because it often goes away on its own. CIN 3 includes severe dysplasia and carcinoma in situ and is treated, because it is highly likely to develop into invasive cancer.
