Screening for TCT and HPV costs about$450. Because cervical cancer is a preventable and treatable disease and its onset has stages, cervical cancer screening is especially important. A large number of studies have confirmed the relationship between persistent high-risk HPV infection and the onset of cervical cancer. Therefore, for married women, regular cervical cancer screening is recommended for early detection of cervical lesions, which can largely reduce the incidence and mortality rate of cervical cancer. For women younger than 30 years old, TCT surveillance is recommended every three years, while for women older than or equal to 30 years old, combined screening with TCT and HPV is recommended. There are three stages of disease prevention, the first one, etiological prevention. The second stage, early detection, early diagnosis, and early treatment. The third stage, symptomatic supportive treatment. So far, only cervical cancer can be prevented at the first stage, that is, the advent of HPV vaccine for cervical cancer can protect women from cervical cancer to a large extent.
