Grove Diagnostic Imaging to work with referring physicians and the Rancho Cucamonga community to explain the law’s impact.

Digital MammographyGrove Diagnostic Imaging, operated by a wholly-owned subsidiary of RadNet, Inc., which manages a network of outpatient imaging centers, announced the importance of working with referring physicians to educate women about the California Breast Density Notification Law that will take effect on April 1, 2013. The law requires doctors to inform women, classified as having dense breast tissue on a screening mammogram, that dense breast tissue may make it more difficult to detect potentially cancerous lesions in their screening mammography imaging study.

California will join Connecticut, New York, Texas and Virginia with a breast density notification law. Radiologists classify breast density into one of four types using the BI-RADS (American College of Radiology Breast Imaging Reporting and Data System) scoring methodology.

  • Fatty (10 percent of women)
  • Scattered fibroglandular densities (40 percent of women)
  • Heterogeneously dense (40 percent of women)
  • Extremely dense (10 percent of women)

“A woman’s breast density is largely inherited but may vary over time due to age, hormones, diet or selective estrogen receptor modulators (e.g. tamoxifen),” said Grove Diagnostic Imaging Medical Director of Breast Imaging Priscilla Wong, M.D. “Depending on the specific nature of a women’s case, additional breast imaging may be recommended. However, as the topic of breast density remains controversial, it’s important for women to speak with their doctors to ensure they receive care appropriate for them.”

Grove Diagnostic Imaging provides two imaging modalities that have been established as additional screening tools for breast cancer, breast MRI and screening breast ultrasound. Review of the radiology literature shows that breast MRI has the highest sensitivity (success rate) to identify a breast cancer tumor. However, breast MRI has a lower specificity (proportion of false positives) and may create false positives that will cause some women to undergo biopsies with benign results.

Breast MRI and screening breast ultrasound studies entail additional time, cost and worry. These two imaging modalities may not be covered by insurance as insurance plans differ. It is important for referring physicians and patients to check insurance plans for coverage of additional studies. Physicians must weigh the risks and benefits for each patient’s specific situation to determine the best option.

Patients classified with either heterogeneously or extremely dense breast tissue will receive a letter with the following lay summary:

Your mammogram shows that your breast tissue is dense. Dense breast tissue is common and is not abnormal. However, dense breast tissue can make it harder to evaluate the results of your mammogram and may also be associated with an increased risk of breast cancer.

This information about the results of your mammogram is given to you to raise your awareness and to inform your conversations with your doctor. Together, you can decide which screening options are right for you. A report of your results was sent to your physician.
