Cervical cancer is one of the most common cancers in women, with 85% of cervical cancer deaths occurring in low- and middle-income areas with low censuses. Through screening, cervical cancer is the only gynecological cancer that can be detected early and can be cured. Early screening found that cervical precancerous lesions are the key to prevent cervical cancer. About 2.4 billion women worldwide need census of cervical cancer and precancerous lesions each year, with only 160 million (about 7%) actual censuses. In China, due to the lack of pathology doctors and cytology testing equipment, the census rate of cervical cancer is only 1%. Therefore, the intelligent screening system to reduce the burden on pathologists, to improve screening prevalence, prevention and treatment of cervical cancer is of great significance.
