Among cervical lesions, the most frightening is cervical cancer, especially advanced invasive cancer of the cervix, which can seriously endanger patients’ lives. In contrast, cervical intraepithelial neoplasia, or CIN, is a precancerous lesion of the cervix. Since moderate cervical intraepithelial neoplasia (CIN2) and severe cervical intraepithelial neoplasia (CIN3) have a high chance of turning into cervical cancer, the lesions should be removed surgically to prevent the disease from occurring in the first place. At present, there are three common clinical approaches, high frequency electric knife performing cervical loop excision (LEEP), cold knife cervical conectomy (CKC), and total hysterectomy. These three treatment methods? Each has its own advantages and disadvantages and the appropriate procedure should be decided according to the patient’s condition and the surgeon’s surgical skills. LEEP is the first choice, and the biggest advantage is that the patient’s surgical damage is small, the patient does not need to be hospitalized, the cost of the procedure is low, the psychological burden is small, and the impact on future menstruation, sex life, and pregnancy is small.
