Dense Breast Tissue

During the 2013 legislative session, Senate Bill 420 was passed which directs health care facilities offering mammography services to provide an advisement in the form prescribed by the Oregon Health Authority to patients with dense breast tissue. Specific advisement language is required, including the possibility of the need for supplemental imaging based on the patient's risk factors. This information is to be provided within the lay person summary mammography report issued to the patient.


This rule became effective January 1, 2014

The following language is required to be included within the lay summary report when dense breast tissue has been determined by a radiologist:

Your mammogram shows that your breast tissue is dense. For most women, breast density decreases with age, but in some women, there is little change. Dense breast tissue is common and is not abnormal. However, dense breast tissue can make it harder to find cancer on a mammogram and may also be associated with an increased risk of breast cancer. This information is provided to you by Oregon State Law to raise your awareness and to promote discussion with you heath care provider about your own risk for breast cancer. Together, you can decide if additional breast imaging tests such as a breast ultrasound, Magnetic Resonance Imaging (MRI), or Breast-Specific-Gamma-Imaging (BSGI) would be beneficial based on  your risk factors and physical examinations. A report of your results was sent  to your health care provider.

The facility is required to have a written policy of when and how they will communicate cases of extreme breast density and heterogeneous breast density.

Information for patients and providers can be found on the Oregon Breast & Cervical Cancer Program (BCCP) website.
