Total hysterectomy for precancerous cervical lesions generally does not pose a cancer risk, while partial hysterectomy still poses a cancer risk. Pre-cancerous cervical lesions are categorized into partial removal and total hysterectomy. The extent of removal varies with different surgical options, and so do the chances of developing cancer at a later stage. If only a conization of the uterus is performed, there is still part of the cervix inside the body, which may become cancerous due to incomplete removal of the cervix or infection with HPV virus at a later stage. However, if total hysterectomy is performed, the uterus and cervix are gone, and there is no more diseased tissue and parts, so naturally there is no problem of cancer in later stages. However, this kind of surgical plan is generally not recommended, and it is mostly for patients with severe high-grade squamous epitheliopathy. It is recommended that patients diagnosed with precancerous cervical lesions should go to the hospital in time, and choose the appropriate treatment according to the specific situation under the guidance of the doctor.
