Linda:  Since I'm behind in postings (surgery and grading final exams),
I'm unclear as to who originally posted this, but the small calcifications
sound like "milk dust."  Recently, there's been a bit more research on
post-menopausal women who breastfed for an extended time.  Apparently,
small amounts of milk remain in the breast and turn to milk dust.  This is
not necessarily a precancerous condition.  The problem is that we don't
have many radiologists or gyn-onocolgists who are used to reading the
mammograms of women who breastfed for an extended time.  So, you probably
want a reference, but I'm too overwhelmed to find one at this moment
(sorry).  You might try Dr. Susan Love or the Center for Breastfeeding
Information (LLLI) and ask for a search on "milk dust".
