Abstract:
CIN I and CIN II can be treated by colposcopy-guided biopsy. Control examinations must be made every six months. Persistence of a CIN II lesion is an indication for conization. Some CIN III cases can be treated by conization, but considering the frequency of residual lesions and insufficient conization, a total hysterectomy is a safer procedure.
