For the treatment of cervical precancerous lesions, it is necessary to understand whether it is a low-grade precancerous lesion or a high-grade precancerous lesion.

If it is a high level cervical lesion, it is recommended to do cold knife conization of the cervix, which also needs to be done once and three months later to achieve complete cure.
