Severe atypical hyperplasia of the squamous epithelium of the uterine cervix is the most serious type of precancerous lesion, and some of them have already started to develop carcinoma in situ, which needs to be treated by cervical conization and total hysterectomy. 1. Cervical conization: for young women with reproductive needs who need to preserve the uterus, cervical conization can be performed, with regular checkups after the operation. 2. Total hysterectomy: If a woman is already menopausal and has no need for reproduction, she can undergo total hysterectomy to minimize the possibility of cancer. Clinical findings of severe atypical hyperplasia of the squamous epithelium of the uterine cervix, need to consult a doctor in a timely manner, through the examination to determine the specific state of the disease, under the guidance of the clinician to carry out standardized treatment.
