Treatment depends on the type and severity of the precancerous changes: - CIN: May be monitored with regular Pap smears if mild. More severe cases may require cryotherapy or LEEP (Loop Electrosurgical Excision Procedure). - Endometrial Hyperplasia: Treatment options include hormonal therapy (such as progestins) or surgical options like a hysterectomy in severe cases. - VIN: Treatment may involve topical medications, laser therapy, or surgical excision.
