Cervical conization is the most important measure when dealing with CINIII. It is an essential tool and process for both diagnosis and treatment of cervical lesions, and it can be said that patients with CINIII who have not undergone this process are likely to take some detours in their treatment. After conization, the postoperative pathological results are the most important, and the corresponding treatment according to the results is even more important, which is one of the reasons why conization must be done. Through conization, it is clear that patients who have CINIII can choose hysterectomy if they do not have fertility requirements and are older; while for those who are younger and have fertility requirements, the uterus can be preserved for close follow-up; and when conization confirms that the patient has cervical carcinoma in situ, hysterectomy is usually required if there is no fertility requirement, but for those who still have fertility requirements, they can try, under close surveillance When conization confirms early invasive carcinoma with fertility requirements, radical hysterectomy with uterus preservation and artificial pregnancy assistance can be considered, while for patients without fertility requirements, hysterectomy and radical cervical hysterectomy can be performed.
