This usually happens after breast surgery. The typical scarring can be seen on the skin. Underneath the skin, the usual arrangement (pattern) of the glandular tissue can be distorted. This is also call archetictural distortion.
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.
