Cervical intraepithelial neoplasia. Therapeutical trends.

CIN is an intraepithelial alteration of unpredictable development. Its presence may require in the case of CIN 1 only periodical colposcopy and cytology, while in the presence of CIN 2 or CIN 3 a complete removal of the lesion is necessary. Surgery must be "personalized". Sometimes when the excision is large, it may be necessary to follow with hemostatic suture in order to reconstruct the portio.
