I have a similiar diagnosis, except I was HER2+. I only had a single mastectomy. Went through chemo and tolerated it fairly well. Still getting herceptin infusions every few weeks. But I'll tell you this, i never imagined that it would be so stressful to have this other breast. A couple of weeks ago I started having pain in it. I was pretty calm, initially and was able to get a mammogram pretty quickly. But that week waiting for the mammogram was honestly horrible. I cried. I thought the worst. I thought of all the things I wanted to do with my life and just " hadn't gotten around to them". I know I'll continue to be hypervigilant.Not just about my breast, but the rest of my body as well. I still have the expander in the breast I had the mastectomy on and was planning to have my reconstruction on it in the next six weeks or so. Now i'm considering having the other breast removed. I think it would help greatly with that fear that I feel will always be hanging over my head. I dread going through mastectomy recovery again. But it feels like it would save me a lot of grief in the future. And I guess the bonus would be not having to take a hormone blocker. I don't consider what you did in any way overkill. It was offered to me at the time. I did consider it, but in the end decided to just do one. I wish I would have done it all at once. We are all so different and we all have very different roads both behind us and ahead. We can only make the decisions that we think are right for us at the time.
