Cervical conization is usually not cancerous. Cervical conization is known as a conical cervical resection. It is usually applied to precancerous lesions of the cervix, that is, cervical intraepithelial neoplasia. The purpose is to take the specimen from the conization and do further pathological examination to confirm whether there is cancer or not. 1. Cervical conization is mainly to take out the diseased tissues for pathological examination to clarify the specific nature of the cervical lesions, and it is mainly applicable to patients with high-grade squamous intraepithelial neoplasia, i.e. moderate-to-severe cervical intraepithelial neoplasia. 2. At present, cervical cancer is mainly related to HPV infection, especially high-risk HPV infection, such as HPV16 and HPV18. If HPV-positive patients undergo regular review after cervical conization and find that HPV has turned negative, the chance of developing cancer is low. If there is still persistent HPV infection after cervical conization, regular follow-up is required and colposcopy is needed if necessary. After cervical conization, patients need to go to the hospital every year for cervical cytology screening and HPV screening to treat any cancerous lesions promptly.
