How many tests are involved in cervical cancer screening?

Cervical cancer screening generally involves the following tests: 1. Cervical cytology (TCT): This is the basic method for early cervical cancer screening. It involves collecting exfoliated cells from the cervix to check for the presence of abnormal cells. This test has high specificity but relatively low sensitivity, so regular follow-up tests are necessary. 2. High-risk HPV testing: HPV virus is the main cause of cervical cancer. High-risk HPV testing can determine whether an individual is infected with high-risk HPV viruses, especially high-risk HPV subtypes. When used in combination with cytology testing, it can improve the accuracy and reliability of screening. If abnormalities are found in either of the above tests, further colposcopy and cervical biopsy may be required to confirm the diagnosis.
