Married women are recommended to undergo cervical liquid-based cell examination once a year. If the result is negative for three consecutive years, the examination period can be extended, such as once every 3-5 years. For those with special medical history, such as those with abnormal TCT test before, or those with history of cervical precancer surgery or cervical cancer, the frequency of examination should be increased to once a year; for those with low immunity, such as those who have been infected or carriers of HIV, the testing time should also be shortened to at least once every six months. For those with abnormal cervical cancer screening results, they must undergo the next testing and treatment under the guidance of professional doctors, such as HPV testing or cervical biopsy, colposcopy, etc.
