If the pathological examination of the cervix reveals CIN3 with glandular involvement, it means that the lesion is relatively deep and if there is no requirement for pregnancy planning, it is better to have a total hysterectomy to avoid the development of cervical cancer. If you still have a strong demand for family planning, you can only undergo conical excision of the cervix and cold knife conization. The excised tissues will be sent for pathological examination to further understand whether there is a possibility of cancer.
