N.J. Stat. § 26:2-184.3
A facility that provides a mammography report pursuant to the federal Mammography Quality Standards Act, 42 U.S.C. s. 263b, shall include the following information, at a minimum, in the mammography report sent to the patient and the patient's health care provider: "Your mammogram may show that you have dense breast tissue as determined by the Breast Imaging Reporting and Data System established by the American College of Radiology. Dense breast tissue is very common and is not abnormal. However, in some cases, dense breast tissue can make it harder to find cancer on a mammogram and may also be associated with a risk factor for breast cancer. Discuss this and other risks for breast cancer that pertain to your personal medical history with your health care provider. A report of your results was sent to your health care provider. You may also find more information about breast density at the website of the American College of Radiology, www.acr.org."
