SCATTERED AREAS OF FIBROGLANDULAR DENSITY
This phrase is used in the standard sentence, "There are scattered areas of fibroglandular density." It means that the breast is composed of 25%-50% glandular tissue. Cancer looks like a white spot on a mammogram. Normal glandular tissue is also white on a mammogram. When there is more glandular tissue in the breast, cancer is harder to see/detect. As an analogy, imagine trying to spot a white bear when it is snowing outside (in the North Pole). If it is snowing lightly, the white bear should be easy to detect. If there is a raging snow storm (blizzard), the white bear will be difficult to detect. Back to the mammogram...When there is 25%-50% glandular tissue, cancer can be "hidden" in the glandular tissue, but often , cancer will be detected, if it is present.
