Cervical pre-cancerous lesions grade 2~3 are usually recommended to be conically cut, and ablation therapy can also be chosen according to the situation to reduce the risk of malignant lesions. Grade 2~3 cervical precancerous lesions are high-grade lesions with a greater risk of developing invasive carcinoma. Therefore, this situation needs to be intervened as soon as possible. If the scope of the cervical lesion can be exposed and observed adequately under colposcopy, cervical conization or ablation treatment can be considered; if the overall scope of the lesion can not be seen adequately, only conization can be performed, and cold knife conization or Lipo knife conization can be chosen. Meanwhile, the specimen of conization needs to undergo further pathology to confirm the diagnosis. It is recommended to consult a professional doctor and choose the appropriate treatment as soon as possible for standardized diagnosis and treatment.
