HPV infection requires a combination of TCT and HPV cancer screening to determine if there is HPV infection. Although colposcopy is one of the gynecological endoscopes, which can be used for the diagnosis of various cervical diseases and diseases of the reproductive organs, it is necessary to perform a cervical biopsy under colposcopy to determine whether there is any HPV infection and whether there is any chance of precancerous lesions. In the case of HPV infection, a cervical biopsy is performed to determine whether it is benign or malignant. If it is a low-risk type of intraepithelial neoplasia, suggesting benign, according to their own situation, they can carry out anti-viral treatment with vaginal plugs, and after six months of HPV infection, they have to be rechecked regularly. If it is a high-grade intraepithelial neoplasia, it cannot be treated with drug insertion, and it is necessary to perform cervical conization to determine whether the margins are negative or positive, and then decide on the next step of treatment.
