Do you have dense breasts?

Imagine going in for your routine mammogram and being told you have dense breasts. You may wonder what does that mean?

Breasts contain glandular and fatty tissue. And when a patient’s breasts are mostly glandular tissue and little fat tissue, they are considered dense breasts.

Dr. Charisa M. Spoo, a medical director at Advocate Christ Medical Center in Oak Lawn, Ill., explains that breasts are given a density based on how they appear on a mammogram.

The 4 levels of density are:

Type A: Entirely fatty breast – indicates the breast is entirely composed of fatty tissue.

Type B: Scattered fibroglandular breast – indicates there is scattered dense tissue throughout the breast.

Type C: Heterogeneously dense – indicates half the breast is dense and the other half contains non-dense tissue.

Type D: Extremely dense indicates the entire breast tissue is dense.

Type C and D are categorized as dense breasts.

“Dense breasts tissue can be more challenging to interpret. But 3-D technology allows the mammographer to evaluate the breast tissue in detail,” says Dr. Spoo. “In coordination with a whole breast ultrasound or Automated Breast Ultrasound, we can evaluate the breast with different modalities for a complete evaluation of breast cancer.”

“The American College of Radiology recommends for people that have dense breasts to also get an automated breast ultrasound along with a mammogram,” shares Dr. Spoo. “It examines your tissue in a different way in evaluation for breast cancers.”

Although there are no symptoms of having dense breasts, Dr. Spoo shares how important it is to do a monthly self-examination to be familiar with your breast. “Dense breast may feel lumpy and bumpy, but it is important to be in tune with your breast. It may be difficult for someone to know if they have dense breasts, so it is best to have a clinical exam by your physician and a mammogram,” says Dr. Spoo.

    What if my mammograms show dense breasts some years but not in others?
