@joannie No matter what the result is for me, it doesn't follow that my kids have the same (50%) and they cannot be tested until they are adults and make that decision. For me, she did tell me that it has life insurance implications but that cancer trumps that, anyway.
@kmakm My reaction is a bit strange. It's been something that has been lurking in the background all of the time but except for my original GP (who looked at it from the perspective that 100% of my siblings had breast cancer), the possibility has been downplayed. Perhaps it was just to get me through active treatment as my oncologist said that, in my situation, he wouldn't normally refer to the geneticist until after chemo and radiation. To hear the geneticist say that, regardless of what the tests show, she believes there's almost certainly an hereditary gene involved (1 in 4 chance of it being picked up at this point in time), just confirmed what I have always suspected, but it did make me very shaky.
