Breast Density
Understand what it is and why it matters
How do I find out my breast density?
Breast density is determined at the time of the interpretation of your mammogram by a radiologist. There are four categories of breast density that range from almost entirely fatty tissue to extremely dense. The doctor who referred you for the mammogram will discuss your results and explain where you fall on the density scale. In addition, you will receive a letter in the mail providing you with this information, as per New York state law.
How is breast density measured?
4-level density scale:
A – Almost entirely fatty
B – Scattered areas of fibroglandular density
C – Heterogeneously dense
D – Extremely dense
Why is learning my breast density important?
Women who have dense breasts have a higher risk of developing breast cancer. Dense breast tissue can also make cancers more difficult to see in a mammography and more difficult to feel during a physical examination.
If I have dense breasts, should I still have regular mammograms?
Yes. Mammography is still the best single test available to detect breast cancer, and has been proven to save lives in women of all breast types. Ultrasound may be helpful as an additional test for women with dense breasts, but should not be used in place of mammography. Certain kinds of cancers are only visible on mammograms and will not be detected on ultrasound.
Are there other breast screening options for women with dense breasts?
Yes. Research has shown that for women with dense breasts, ultrasound (or “sonography”) can help improve breast cancer detection. For some women who are at higher-than-average risk due to family history, genetic conditions or other factors, breast MRI may be recommended. Women who have dense breasts or think that they may be at increased risk should consult their physician.
All women – even those with entirely fatty breast tissue and low risk for breast cancer – should get annual mammograms beginning at age 40, according to the American College of Radiology.
Will my breast density change as I age?
For some women, breast density will decrease with age, especially after menopause. However, for many, breast density does not change.
If I don’t have dense breast tissue, am I at lesser risk for breast cancer?
Breast density is just one of many factors that determine a woman’s risk of developing breast cancer. Other factors include family history, genetic conditions, previous radiation treatment and previous biopsies demonstrating high risk conditions. Women should discuss their breast cancer risk with their personal physician to determine which screening tests are appropriate for them.
