Highly advanced CIN lesions can be treated. If a highly diseased lesion is not actively treated, about 20% will progress to invasive carcinoma of the uterine cervix. In order to prevent the occurrence of invasive carcinoma of the uterine cervix, it is necessary to actively carry out treatment, and the commonly used treatment is conical resection of the uterine cervix, which has a therapeutic and diagnostic function. If all the lesions are cut cleanly after conical excision, it means that it has played a therapeutic role. If there is invasive cervical cancer in the resected tissue, the next step is to expand the scope of surgery. The specific surgical method and the scope of surgery will depend on the patient’s age, whether there are any fertility requirements and the severity of the lesion. Therefore, highly CIN lesions can be completely cured through active treatment. Even if it develops into cervical cancer, the cure rate can reach more than 90% if it is early cervical cancer, so there is no need to worry.
