Cervical grade II-III lesions are high-grade cervical precancerous lesions, which will progress to cervical cancer in about 2-3 years if left untreated and unintervened. Once cervical grade II-III lesions are detected, patients are advised to take active treatment, the most common method is to undergo conical hysterectomy, and most patients can achieve cure if there is no abnormality in postoperative pathological examination. If high-grade cervical precancerous lesions fail to take timely and effective treatment, they can be transformed into cervical cancer in 2-3 years if they continue to develop, which will then cause more physical damage and mental stress to patients. Therefore, patients diagnosed with cervical grade II-III lesions are recommended to go to the gynecology department of regular hospitals in time for early surgery, which has a very high cure rate and good prognosis. Patients also need regular post-operative review to find out whether there are still lesions in the cervical epithelium and whether there is high-risk HPV infection.
