Michigan Breast Density Notification Law

Effective June 1, 2015, Michigan law requires that mammography service providers inform patients if they have “dense breast tissue” on any mammographic study. Specifically, the law requires the provider to relay the following statement to individuals with breast density:

“Your mammogram shows that your breast tissue is dense. Dense breast tissue is very common and is not abnormal. However, dense breast tissue can make it harder to find cancer through a mammogram. Also, dense breast tissue may increase your risk for breast cancer. This information about the result of your mammogram is given to you to raise your awareness. Use this information to discuss with your health care provider whether other supplemental tests in addition to your mammogram may be appropriate for you, based on your individual risk. A report of your results was sent to your ordering physician. If you are self-referred, a report of your results was sent to you in addition to this summary.”

Within the legislation, “dense breast tissue” means heterogeneously or extremely dense breast tissue as defined in nationally recognized guidelines or systems for breast imaging reporting of mammography screening including, but not limited to, the breast imaging reporting and data system established by the American College of Radiology.
