Breast Density

Breast density is determined from your mammogram. Your report from our office will include your breast density type:

A. Almost entirely fatty

B. Scattered areas of fibroglandular density

C. Heterogeneously dense

D. Extremely dense

The new law requires patients with heterogeneously dense and extremely dense tissue to be informed as they may be candidates for additional screening tools such as ultrasound or MRI (patients with family history and other risk factors may qualify). The denser the tissue, the more difficult it can be for a radiologist to interpret.

Breast density comparison

If we find you have a dense pattern (Heterogeneously dense OR Extremely dense), your result letter will recommend that you talk to your referring health care provider about your breast cancer risk and discuss whether you may benefit from additional testing. If you and your primary care physician wish to have a screening ultrasound because your breast tissue is dense, EWBC can provide that service at any  of our five locations. Patients may be responsible for payment, depending on insurance coverage.

Women with breast density of “heterogeneously dense” or “extremely dense” have been shown to be at increased risk for breast cancer by several studies on breast density published over the last 20 years. The degree of risk is controversial as studies to date have reported drastically different results. We believe there is a considerable risk for these women, even without any other risk factors present (such as family history of breast cancer). The risk is based on the masking of breast cancer (the inability to identify an abnormality that may be a malignancy) in dense breast tissue as well as the inherent higher risk of cancer for women with this type of tissue.

The percentage of women we care for yearly with this type of breast density is approximately 43% of women of all ages having a routine mammogram. In January of 2013, New York State adopted the law of informing patients and their practitioners of breast density. In the last year we have seen a trend of women with this type of breast tissue return for a screening breast ultrasound after notification was given to them by our staff and our radiologists.

In the women that do return, we are discovering mammographically non-visible cancers at three per 1000 women, which is comparable to published studies performed on screening ultrasound in average risk women. We believe screening ultrasound is a reasonable, accessible tool for breast cancer detection to be used in addition to the screening mammogram.

If your last mammogram at our facility identified your tissue type as dense, we offer screening ultrasound at all our offices.

Please be aware some insurances do not cover screening ultrasounds or may apply the fee to your deductible plan.
