Hello again--
Thanks very much for all the good wishes and info. I can't get to this site very often right now (just not much discretionary internet time) but I DID read all responses.
Main thing I want to mention is that while I'm terrible with supplement compliance, the D3 thing is something that really stuck with me from this site, and after doing 5k IU for a while I can honestly say this is one of the few supplements that makes me feel like I can feel the difference. I just feel better, emotional and mental resilience much better (or else this cancer thing might well have crushed me), haven't been sick in...don't remember how long, etc. This is about a year and a half on 5k. When my parents moved up here from Florida a year ago, since Mom wasn't doing well mentally at the time (like a lot of people the recession wiped them out), I had her start taking the D3 immediately also--I figured moving from Florida to a place with actual winter was going to be rough and this might help. So in other words, she's been on the D3 for quite a while now. I'll make sure it stays that way.
Nancy, not sure what kind of HRT, and I'd be surprised if she remembers, but I'll ask.
She's 63, btw.
They've scheduled three appts tomorrow: oncologist, radiologist (I may have the slightly wrong word there) and surgeon. Both my sister and I will be there and I think I'm going to take a notepad in. So by this time tomorrow I should know more about how they are actually going to proceed.
She's 'basically' in good spirits, if a little pissed off at the universe, although like any Mom she is probably hiding the worst of her reaction from me. We're to the point of making jokes about blond wigs and fake boobs, so that's good. (Obviously we are really hoping neither becomes necessary, but what can you do.)
She keeps wanting to do retail therapy, though, and I now have way too many pairs of winter boots.
Thanks again--will be back with more info when I have it.
Edit: Oh, one more question. I really don't want to google this because I can imagine the hits I will get. Mom's always cooked pretty high fat. Was there ever really any proven link between dietary fat and breast cancer? (I followed the vitamin d council link and one of the first lines was: "Certain diets help to prevent it, such as diets high in vegetables and fruit and low in fat." I know they probably have to say this, but I honestly don't know.)
