CIN 3

Severely abnormal cells are found on the surface of the cervix. CIN 3 is usually caused by certain types of human papillomavirus (HPV) and is found when a cervical biopsy is done. CIN 3 is not cancer, but may become cancer and spread to nearby normal tissue if not treated. Treatment for CIN 3 may include cryotherapy, laser therapy, loop electrosurgical procedure (LEEP), or cone biopsy to remove or destroy the abnormal tissue. CIN 3 is sometimes called high-grade or severe dysplasia. Also called cervical squamous intraepithelial neoplasia 3.
