@wyowyld I wasn't aware there was such a thing as being "completely comfortable" with any decision in this difficult situation we all find ourselves in, but you've managed to do it, so, good for you! I am also stage 1a & 72 years old & did the 5-day radiation. I'm going to start a half-dose (10 mg) of Tamoxifen this week & see how it goes. I feel I need to at least try, even if it's a reduced dosage. But I understand your point & as you say, I wish for all of us the best possible outcomes!
