Squamous cell carcinoma of the cervix, in which the surface squamous epithelium shows in situ carcinoma-like changes, usually refers to in situ carcinoma-like changes of the cervix, which belongs to the early stage of the tumor, and needs to be dealt with accordingly with the combination of age and demand, if there is a demand for pregnancy preparation, cervical conotomy can be done; if there is no demand for pregnancy preparation, uterine excision can be done directly. 1. Young women with the need to prepare for pregnancy can consider cervical conization surgery to deal with the corresponding changes. After the conization surgery, the resected tissue should be pathologically diagnosed to assess the degree of malignancy of the disease, and observe the status of the margins, and there is no cytopathic lesions that require regular review and close follow-up. 2. Middle-aged and elderly women who do not need to prepare for pregnancy can choose to undergo total hysterectomy directly, which can avoid tumor recurrence and metastasis to the greatest extent possible, and undergo regular review every year after the operation. Cervical carcinoma in situ belongs to the earliest stage of cancer, and most of them can be clinically cured after surgical resection. Once the lesion recurs during the review period, it is necessary to seek medical treatment in time and carry out standardized treatment under the guidance of clinicians.
