Abstract: The standardized diagnosis of cervical cancer is a prerequisite for standardized treatment of cervical cancer. The etiology of cervical cancer is clear，and its occurrence and development is a gradual process with its distinctive characteristics. It usually takes 8 to 10 years from continuous HPV infection to intraepithelial neoplasia，and then to invasive cancer. The focus of diagnosis at this stage is to screen through HPV detection，and sometimes assisted cytopathological examination is needed. The stage of invasive cancer progresses rapidly，and the diagnosis mainly depends on histopathological biopsy and radiographic examination，such as colposcopy，histological bite examination，endocervical canal curettage，conization，CT or MRI. The main purpose of pre-screening is to find treatable precancerous lesions that can develop into invasive cancer so as to reduce the morbidity，mortality and treatment-related complications of cervical cancer，and another purpose is to find early invasive cancer. All the methods adopted in the later stage of invasive cancer are to make a clear diagnosis and staging in order to make reasonable and accurate treatment decisions.
