Right on the heels of Ohio, this week Michigan became the 21st state to enact breast density inform legislation. Governor Snyder signed Michigan’s breast density inform bill into law (SB 0879) and it becomes effective June 2015.

The first density reporting law was enacted in Connecticut in 2009.  Another eight states are due to introduce density reporting legislation in 2015, according to Are You Dense Advocacy, Inc, a non-profit that advocates for universal density reporting through state and federal law. The federal density reporting bill in the Senate and House is due for reintroduction in the new Congress soon.
