LCIS ER+/- and Tamox

Okay, here's a thought that I'd very much like input on. Have you guys had your LCIS to test if it is Er+ or Er=? I don't think they usu. do that, right? At least at my Kaiser, I was told that is NOT the standard-of-care. However, I read Tamox is only indicated for Er+, so I said that'd be ridiculous for me to go on a medication for 5 yrs, suffer side effects, run risk of endometrial cancer, and the whole while it turning out the med was contraindicated if I had Er- LCIS cells. So, breast coordinator said she'd talk to the pathologists and they might make exception for me. I sure hope they do! That just seems CRAZY to me. Am I missing something??? They'd willingly cut off both my boobs (PBM), although i think they'd advise against it, but they won't test cells for Er+/- prophelactically to guide future treatment interventions,w hich for LCIS is all about prevention? We should all protest with all our doctors and insist! I hope none of you are taking tamox and have ER- cells without knowing. Oddly, I read somewhere that pre-menopausal women often have (more often have?) ER neg. cells while post-menopausal tends to be Er+. Maybe that's why they don't test? bc a neoplasia can change over time? Anyway, this was stunning to me, but I"m new to all this so I could well be missing something (she did say they can't test LCIS for her2/neu b/c it's not a cancer, but it was more like they can't, not that they don't or won't as with ER/Progesterone postive/negative.----Paula
