Cervical Intraepithelial Neoplasia (CIN)

Cervical intraepithelial neoplasia (or CIN) refers to the presence of abnormal cells seen on the cervical cytology smear. These abnormal cells are obtained from the lining of the outer cervix and can range from mild to severe changes. A diagnosis of CIN changes is not cancer. However, the severe form of dysplasia can be considered a precancerous condition and may eventually progress to cancer in several years if not treated.

The cervical cytology smear was previously referred to as Pap smear. Currently, the newer cervical cancer screening uses a liquid based cytology and the commonest one used are: Thin Prep or Sure-Path. These are better and more accurate compared to the conventional Pap smear test.
