If the cervix has precancerous lesions, it is not allowed to take cervical cancer vaccine, and it is recommended to give treatment. If it is low grade precancerous lesion, it can be treated by laser therapy, microwave therapy or freezing method, which mainly makes the lesion epithelium necrotic and fall off, and then new epithelium grows back to achieve the purpose of cure. If it is high grade pre-cancerous cervical lesion, it is recommended to do cold knife conization surgery for treatment. After the surgery, it is necessary to have a regular review, and if 3 consecutive examinations are negative, it can be considered to receive the cervical cancer vaccine. The indications for cervical cancer vaccination should be strictly controlled, and after the 3 doses of cervical cancer vaccine have been fully administered, regular rechecks should be conducted for cervical epitheliopathy and high-risk HPV infection.
