If the cervix is infected with HPV (human papillomavirus) and does not turn negative one year after the conization procedure, a colposcopic biopsy is necessary.
Cervical conization surgery is performed to prevent localized malignant changes in the cervix, and is usually performed after infection with high-risk HPV and the development of high-grade intraepithelial neoplasia of the cervix, to further define the extent of the lesion and to provide a basis for the next stage of treatment.
Generally, the HPV virus will become negative in most cases some time after the procedure, but if it continues to be negative, it may cause malignant epithelial lesions, and therefore a biopsy is still needed.
If the cervix is still not HPV-negative one year after the conization surgery, the patient needs to go to the hospital in time and have the appropriate diagnosis and treatment under the guidance of the doctor.
