Breast density: The other ABC’s.

According to the new guidelines, there are 4 levels of breast density7. If you have denser breasts, you have a greater risk of breast cancer, and they can be more difficult to scan for cancerous tumors. The good news is, there are many advanced screening options, such as 3D mammograms to give you and your doctor a clearer picture of your breast health, even if you have dense breasts.
