Summary: Breast cancer screening guidelines continue to spark controversy in part due to lingering uncertainty about the effectiveness of mammography at reducing breast cancer mortality. The CISNET consortium is an NCI-funded collaboration of independent groups formed to use modeling methods to provide insight into cancer screening and treatment interventions in the US. Over the past decade, the consortium has conducted a series of analyses designed to address evidence gaps in breast cancer screening policy. I will provide an overview of this work, including insights on the role of simulation modeling in informing current breast cancer guidelines and lessons learned from our collaborative modeling efforts.
