Cervical intraepithelial neoplasia generally refers to cervical intraepithelial neoplasia, which usually does not matter, but needs to be taken seriously. Cervical intraepithelial tumors are precancerous lesions, including cervical atypical hyperplasia and cervical carcinoma in situ. Patients generally have no obvious symptoms, and some patients will have increased leukorrhea, leukorrhea with blood contact bleeding and cervical hypertrophy, congestive erosion, polyps and other chronic cervicitis manifestations. Most grade I cervical intraepithelial neoplasia is reviewed regularly and does not require treatment. Some grade II and III cervical intraepithelial neoplasia and cervical carcinoma in situ have the tendency of malignant transformation into cervical cancer, which requires cold knife conization, and hysterectomy is recommended if there is no requirement for fertility. Therefore, patients with cervical epithelial tumors should go to the hospital in time, improve the examination, clarify the benign and malignant nature of the tumor, and carry out regular treatment under the guidance of doctors.
