And so the yellow is the fatty plaque, and panel A is a man.

Because it turns out that adipose tissue, fat, is highly angiogenesis dependent.

Our hunter ancestors ate fat, which was transported to the liver and broken down by the lipolytic pathway to deliver fatty acids to the mitochondria (the subcellular structures that burn food to create energy). On the occasion of a big kill, any excess dietary fatty acids were packaged into low density lipoproteins and transported out of the liver to be stored in peripheral fat tissue.

Breast density refers to the relative amount of fat pictured here in yellow versus connective and epithelial tissues pictured in pink.

And, like a tumor, fat grows when blood vessels grow.

Fat derived stem cells are adult stem cells.

If the breast is less than 25 percent dense, that's called fatty replaced.
