Abstract: Cervical cancer with definite pathogenic factors exits longer and reversible premalignant lesions which can be intervened by medical methods to decrease the morbidity and mortality. With the development of cervical cancer screening, more and more women especially young women were found with cervical intraepithelial neoplasia（CIN）. The management and intervention of precancerous lesions is an important link to prevent invasive carcinoma. Combined with American Society for Colposcopy and Cervical Pathology（ASCCP） in 2013 promulgated "2012 Updated Consensus Guidelines for the Management of Abnormal Cervical Cancer Screening Tests and Cancer Precursors", we interpretated the management of cervical precancerous lesions. The uptated guidelines of great importance to direct the clinical practice prescribed the management of CIN and highlighted the follow-up value of co-test.
