cervical squamous intraepithelial neoplasia 3
(SER-vih-kul SKWAY-mus IN-truh-eh-pih-THEE-lee-ul NEE-oh-PLAY-zhuh …)
Severely abnormal cells are found on the surface of the cervix. Cervical squamous intraepithelial neoplasia 3 is usually caused by certain types of human papillomavirus (HPV) and is found when a cervical biopsy is done. If not treated, these abnormal cells may become cancer and spread to nearby normal tissue. Treatment for cervical squamous intraepithelial neoplasia 3 may include cryotherapy, laser therapy, loop electrosurgical procedure (LEEP), or cone biopsy to remove or destroy the abnormal tissue. Cervical squamous intraepithelial neoplasia 3 is sometimes called high-grade or severe dysplasia. Also called CIN 3 and stage 0 cervical carcinoma in situ.
