Minnesota has become the 16th state to enact breast density reporting legislation, with Governor Mark Dayton signing the bill into law on May 21. It is scheduled to take effect August 21, 2014.

The Minnesota Radiological Society commented, “We believe the bill should result in conversations between the patient and her treating clinicians for the appropriate use of testing, including mammography and other breast imaging, in order to reduce the chance of death from breast cancer.”

According to Are You Dense Advocacy, Inc, ten other states have introduced breast density reporting bills this year. Legislation in Rhode Island and Missouri has passed the state legislatures and is awaiting action by their respective governors.
