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".
