Hello! The disease you have is cervical precancerous lesion CIN grade II-III. It is not enough to diagnose carcinoma in situ, LEEP is enough and can be done without hysterectomy. Post-operative follow-up: 1. every three months in the first year after surgery; 2. every six months in the second year after surgery; 3. every year thereafter until the end of your life. It is recommended that you have the HPV test typed for follow-up and treatment. Our hospital has HPV testing for typing.
