[Hopeful]

This is the statement that is fascinating to me:

"But even that may be misleading, Llanos says, because hormone levels may differ between a woman’s two breasts. “Breast cancer usually develops in a single breast, so it is not clear that looking at these hormones in the blood is sufficient,” she says."

So, the million dollar question is, why are gene changes limited to one breast and not the other? Or why do excess hormones collect in one and not the other?

I like things that make me think!
