    Conclusions
    Breast cancer inflicts substantial health and financial burden to women in the United States and worldwide. Screening mammography can reduce the disease burden of breast cancer through early detection and timely intervention. Nevertheless, policy makers designing breast cancer screening programs for the LDN193189 must also consider harms associated with screening mammography, such as false-positive screening results, over-diagnosis and overtreatment. This study applied a micro-simulation model to assess the cost-effectiveness of breast cancer screening guidelines updated by professional societies (e.g., USPSTF and ACS) in the US in late 2015/early 2016. Findings from our model suggested that the most cost-effective screening strategy for women at an average risk of developing breast cancer 
    was a hybrid strategy that starts annual mammography screening at the age of age 45 years and switches to biennial screening be-tween the age of 55 years and 75 years e a strategy that conformed to the updated ACS guideline. Future research should extend the model to explore whether the cost-effectiveness of screening strategies would be altered by the rates of screening adherence, especially among selected population subgroups, as well as among women at higher risk of developing breast cancer.
