Cervical cancer is one of the most common cancers in women, among which 85% of patients died come from low- and middle-income areas in China. Cervical cancer is the only gynecological cancer that can be detected at the early stage and eventually be cured with the help of screening. Early screening of the potential pre-cancerous cervical lesions is key to prevent cervical cancer. Around 2.4 billion women worldwide need to undergo screening of cervical cancer and pre-cancerous lesions each year; however, only 160 million (about 7%) of them conduct the actual screening. In China, due to a lack of histopathology doctors and cytology testing equipment, the census rate of cervical cancer is only 1%. Hence, artificial intelligent screening system is essential to reduce the burden of pathologists and to further increase screening prevalence as well as prevention and treatment of cervical cancer.
