Cervical lesion grade 3 involving the glands may be cured with cervical conization. However, there is a possibility of recurrence. Cervical lesion grade 3 involving the glands suggests that it may be a precancerous lesion of the cervix or cervical cancer in situ, and cervical conization is usually recommended. If the patient’s condition is relatively mild, and after cervical conization, the lesion is removed relatively cleanly, and the excised material is examined by pathological biopsy and no cancer cells or cancerous tissues are seen, the patient may achieve a curative effect and may be cured. After cervical conization, if the residual lesion tissue is found in the cut edge area, and cancer cells or cancer tissues are found in the pathological biopsy of the excised material, the possibility of cure will not be very high, and the disease may even recur, and the disease may not be cured. Patients are advised to seek timely medical treatment so as not to aggravate their condition.
