(SER-vih-kul IN-truh-eh-pih-THEE-lee-ul NEE-oh-PLAY-zhuh …)
Abnormal cells are found on the surface of the cervix. Cervical intraepithelial neoplasia grade 2/3 is usually caused by certain types of human papillomavirus (HPV) and is found when a cervical biopsy is done. Cervical intraepithelial neoplasia grade 2/3 has features of CIN 2 and CIN 3. It is not cancer, but may become cancer and spread to nearby normal tissue if not treated. Treatment for cervical intraepithelial neoplasia grade 2/3 may include cryotherapy, laser therapy, loop electrosurgical procedure (LEEP), or cone biopsy to remove or destroy the abnormal tissue. Also called CIN 2/3.
