[Interpretation of "WHO guideline for screening and treatment of cervical pre-cancer lesions for cervical cancer prevention， second edition"].

Cervical cancer can be eliminated through primary, secondary, and tertiary prevention. Yet it remains one of the gravest threats to women's lives worldwide. In November 2020, the World Health Organization (WHO) officially launched the global strategy to accelerate the elimination of cervical cancer, and underlined that screening and treatment for cervical pre-cancer lesions are two of three key measures for the elimination. In July 2021, WHO issued the second edition of"WHO guideline for screening and treatment of cervical pre-cancer lesions for cervical cancer prevention"to provide important guidance to countries to support them in achieving the target of cervical cancer elimination in all women. This article will interpret the methods for the guideline development, the recommendations/good practice statements on screening and treatment to prevent cervical cancer (including the age to start/stop screening, screening methods, screening interval, the management of screen-positive women and treatment of the precancerous lesions, etc.) and its impact globally, providing reference for the updates of guideline and policy making on cervical cancer prevention and control in China.
