California Breast Density Law

For FAQs about the Breast Density Law, breast cancer risk in women with dense breasts and appropriate ancillary screening tests please see: www.breastdensity.info

The following ancillary breast cancer screening tests are available at the UC Davis Breast Imaging Center (ACC, Suite 500, UCDMC):


Screening Breast MRI
3-D Mammography (also called breast tomosynthesis)

Ancillary screening should be ordered only after an assessment of breast cancer risk and consideration of the risks and benefits of additional screening.

In some UCD patients, 3-D mammography (tomosynthesis) is being performed as part of the routine mammogram. The header on the screening mammography report will state when tomosynthesis has already been performed in a patient with dense breasts.
