cervical intraepithelial neoplasia

Quick Reference

(CIN) cellular changes in the cervix of the uterus preceding the invasive stages of cervical cancer. The CIN grading system distinguishes three stages: CIN 1 (mild dysplasia); CIN2 (moderate dysplasia); and CIN 3 (severe dysplasia, carcinoma in situ). CIN is uncommon after the menopause. Treatment may be by local ablation (e.g. cryocautery, electrodiathermy, or carbon dioxide laser vaporization) or surgical excision (e.g. LLETZ, cone biopsy, or hysterectomy).
