Married women or women with sexual history should indeed undergo cervical cancer screening once a year. The main purpose is to detect whether there are localized epithelial lesions on the cervix, and to deal with them in time once they are detected to reduce the incidence of cervical cancer, so women should insist on having cervical cancer screening once a year. So far, the cause of cervical cancer has been identified and is mainly caused by the persistent infection of high-risk HPV in the cervical epithelium, so TCT test and HPV test should be done to give a comprehensive analysis of both. If there is a high-risk HPV infection, the cervical epithelium should be reviewed regularly if there is no lesion at present, mainly to understand whether the cervical epithelium will be lesioned under HPV infection and to deal with it in time.
