CIN 2+ encompasses CIN 2, CIN 3, adenocarcinoma in situ (AIS), and cancer; CIN 3 (Grade III) Severe dysplasia with undifferentiated neoplastic cells that span more than 2/3 of the epithelium; May involve the full thickness; May also be referred to as cervical carcinoma in situ; CIN 3+ encompasses CIN 3, AIS, and cancer
Carcinoma in situ (CIS) is a group of abnormal cells. [ 1 ] [ 2 ] While they are a form of neoplasm , [ 3 ] there is disagreement over whether CIS should be classified as cancer . This controversy also depends on the exact CIS in question (e.g., cervical, skin, breast).
Examples of epithelial dysplasia include cervical intraepithelial neoplasia – a disorder commonly detected by an abnormal pap smear) consisting of an increased population of immature (basal-like) cells which are restricted to the mucosal surface, and have not invaded through the basement membrane to the deeper soft tissues.

Cervical intraepithelial neoplasia (CIN) means the development of abnormal cells on the surface of the cervix. It is caused by an HPV infection but in most cases, it is resolved by the immune system. However, a small percentage of people might develop a more serious CIN which, if left untreated, can develop into cervical cancer.
Cervical intraepithelial neoplasia (CIN), spanning a bit more than 2/3 of the thickness of the cervical epithelium. Intraepithelial neoplasia (IEN) is the development of a benign neoplasia or high-grade dysplasia in an epithelium. The exact dividing line between dysplasia and neoplasia has been very difficult to draw throughout the era of ...

CIN and SIL are graded from 1 to 3 based on the degree of change observed. CIN 1, 2, and 3 all represent pre-cancerous findings. [14] CIN 1, also known as low-grade SIL, is the most benign finding. This represents very few atypical cells found, and generally, these cells will revert to normal. [14] CIN 2 and 3, also known as high-grade SIL ...
