What does cervical screening check for?

Cervical screening usually refers to cervical cancer screening, primarily aimed at detecting cervical cancer and precancerous lesions. It has the advantages of being non-invasive, convenient, and quick.

Cervical cancer screening typically includes liquid-based thin-layer cytology testing and human papillomavirus (HPV) testing. Liquid-based thin-layer cytology involves collecting cells from the surface of the cervix and then examining their morphology and structure under a microscope to determine whether abnormal cells are present. If abnormal cells are found, further tests such as cervical biopsy may be required. HPV testing mainly involves collecting cervical mucus and vaginal secretions for virological analysis to assess a woman's risk of infection and guide appropriate preventive and treatment measures.

Through cervical screening, doctors can detect and address abnormal cervical cell changes early, effectively preventing the development of cervical cancer. Early detection and treatment of precancerous cervical lesions can prevent disease progression to more advanced stages, thereby improving cure rates and survival outcomes.

Women over the age of 25 who have been sexually active are advised to undergo regular cervical screening to promptly monitor their cervical health and take necessary preventive and intervention measures to maintain their well-being. Those considering cervical cancer screening should first consult with a healthcare provider.
