Have you noticed the term “dense breasts” on your mammogram results? Breast density is more than just a medical term; it’s an important factor in understanding your risk and choosing the right screening plan.
What Is Breast Density?
Breasts are made of fatty and fibroglandular tissue, which includes milk glands and other supportive tissue. A woman’s breasts are considered dense if they have more fibroglandular tissue than fat. Breast density is not something you can feel—it can only be seen on a mammogram.
About 50 percent of women over age 40 have dense breasts, which is significant for two main reasons:
- It can make cancers harder to detect. On a mammogram, both dense tissue and tumors appear white, making it easier for cancer to be hidden.
- It can slightly increase breast cancer risk. Women with extremely dense breasts may have a higher chance of developing breast cancer compared to women with less dense tissue.
If you have dense breasts, your doctor may recommend additional screening tests, such as an ultrasound or MRI, to complement your annual mammogram. These additional tests help radiologists see more comprehensive images of your breasts and can help catch any abnormalities early.
Taking an Active Role in Your Health
If your mammogram results mention dense breasts, consider asking your radiologist or doctor the following questions:
- What is my breast density category?
- Does my density increase my personal risk for breast cancer?
- Should I have additional screening, like an ultrasound or MRI?
- How often should I be screened, and what’s the best method for me?
- Are there lifestyle changes or risk-reduction strategies I should consider?
Dense breast tissue is common and not, by itself, cause for alarm. But knowing your breast density and understanding how it affects screening are important steps in being proactive about your breast health. The earlier breast cancer is found, the more treatable it is.
Remember, breast density is just one piece of the puzzle. Family history, age, genetics and lifestyle all contribute to your overall breast cancer risk. Talking openly with your healthcare provider about your mammogram results and risk factors ensures that your screening plan is tailored to your specific needs.
