The most common methods to screen for cervical cancer are cervical cytology and cervical HPV test, as follows: 1. Cytology includes traditional Pap smear test and the more advanced TCT test. HPV is often classified into low-risk and high-risk HPV according to its effect on cervical epithelial lesions and even the risk of carcinogenesis. In general, the low-risk HPV types are 6, 11, etc., and the high-risk types are 16, 18, 31, 33, etc. If the two screening methods are combined, the detection rate of cervical cancer lesions will be increased. Therefore, it is recommended that women over 30 years of age should undergo regular combined HPV and cytology screening, while for women under 30 years of age, they can undergo regular screening by cervical cytology only.
