What does CIN mean?

CIN stands for Cervical Intraepithelial Neoplasia. It refers to precancerous changes in the cells of the cervix.

  • It is not cancer

  • It affects only the surface layer of the cervix

  • It is usually detected through colposcopy and biopsy

Grading:

  • CIN 1: Mild changes

  • CIN 2: Moderate changes

  • CIN 3: Severe changes (highest risk)

The grade helps doctors decide the best treatment.
