Arizona became the 15th state to pass breast density reporting legislation when Governor Janice Brewer signed a bill on April 17, 2014. The legislation will become effective October 1, 2014. Arizona radiologist Nicole Saphier, MD, championed the legislation, which had unanimous support in both chambers, according to Are You Dense Advocacy, Inc.
Connecticut became the first state in 2009 requiring physicians to notify women who fell into one of the two higher categories of breast density under the BI-RADS scale. A federal density reporting bill was introduced to the House in October 2013, with plans for a companion bill in the Senate this spring. Are You Dense Advocacy is currently working with advocates in 13 other states with active density reporting laws in the 2014 session, according to the organization.
