During population-based screening programs, a 40 years old lady found to have cervical intraepithelial neoplasia. Which of the following is the treatment modality for this patient?

The 5 most common techniques for the treatment of CIN include 2 ablative techniques--cryotherapy and laser ablation--and 3 excisional procedures--cold knife conization, laser cone excision, and LEEP. That these techniques are of equal efficacy, averaging 80-90% success rates in the treatment of CIN. Cure depends on the size of the lesion, endocervical gland involvement, margin status of any excisional specimen, and endocervical curettage results. Ref: Holschneider C.H. (2013). Chapter 48.
