Results A total of 29,111 cases of breast cancer high-risk population that met the research requirements were included in the study,of which 13,760 cases were screened for breast cancer,and the overall participation rate was 47.27%.There were significant regional and time differences in the participation rate of breast cancer screening:the participation rates in the highest and lowest cities were 74.24% and 40.00%,respectively;the overall screening participation rate from 2013 to 2014 was the lowest 40.66% and the highest 51.05% from 2017 to 2018.The multivariate logistic regression analyses suggested:45~64 years old,with junior high school degree or above,smoking or smoking in the past,drinking or drinking in the past,lack of physical exercise,menarche age ＜12 years,menopause,history of fertility,history of benign breast disease,a family history of breast cancer,and a family history of ovarian cancer were more willing to accept breast cancer screening.
