The increasing life expectancy in China is due to the development of medical technology, which relies on advanced detection technology. The incidence of cervical cancer is second only to breast cancer, and the early cure rate of cervical cancer is still relatively high, so timely detection of cervical cancer is crucial. There are several methods for cervical cancer detection and screening. Liquid-based thin-layer cytology is a relatively advanced detection method, and it can be used as a major detection method because of its better examination effect compared with those traditional methods. In addition, there are four other cervical cancer screening methods, the first one is CCT, which is more commonly used, TCT is known as Neuberger’s liquid-based cytology test, which is an American testing technology that was introduced to China in 1999. The diagnosis of cervical lesions is divided into three steps, TCT, colposcopy and pathological diagnosis. most of the TCT is a test, if the TCT test is benign, then the patient cannot do without the later tests. If the TCT test is problematic, the patient can have further testing done and the patient can have colposcopy and pathological diagnosis to further diagnose the condition. When abnormalities are found in cervical cytology smear, colposcopy is needed to identify the lesion. This pathology can provide a basis for surgical treatment Virology is also a very important screening method. HPV infection is the most important cause of cervical cancer and its precancerous lesions. The accuracy of this method is quite high, but it is usually used only in high-risk groups because of its high cost. Overall, cervical cancer is a common malignancy in women and can be screened for by a variety of methods, some of which are more advanced to improve the accuracy of the test. TCT is also an important screening method.
