How is dense breast tissue diagnosed?

Dense breast tissue is diagnosed during a mammogram. A radiologist is a physician who reads X-rays, including mammograms. She/he will describe your breast density based on how your tissue looks on your mammogram. The dense glandular tissue will look white, and fatty tissue will look dark on your mammogram. The more white areas the radiologist sees on the image, the denser the breast.
