Treatment of cervical premalignant lesions (cervical intraepithelial neoplasia; CIN) of different grades is very effective, simple, and safe. The entire transformation zone of the cervix needs to be treated either by an ablative technique (cryotherapy or thermal ablation) or an excisional technique (large loop excision of transformation zone or cold knife conization); the choice of treatment depends on the size and location of the lesion and the type of the transformation zone. The cure rate after ablative treatment of high-grade CIN may be little lower than that after excisional treatment. The simplicity of the technique, low complication rate, and lesser cost make ablative technique the treatment of choice in the low resourced settings for the eligible lesions. In situations where organizing colposcopy and histopathology services is challenging, simple algorithms like screening with visual inspection with acetic acid test and immediate ablative treatment of the visual inspection with acetic acid-positive women has been recommended by the World Health Organization. Such a strategy is effective in preventing subsequent development of high-grade CIN and also ensures high compliance of the screen positive women to treatment.
