You've all given me insights into how I need to be thinking about this question, which is just what I wanted. Also some good sound information. I think I'll be able to have a much better talk now with my oncologist next Wednesday.
My gut feeling is that once I'm more recovered from this traumatic year, I'll probably go ahead and have an elective mastectomy. It seems to me that if you have had it in one lot of breast tissue, how wouldn't the cancer 'know' about and most probably already be in the other lot of breast tissue? It's only that breasts come in two separate lumps but it's all the same to cancer cells, I'd have thought, if anyone can actually understand what I'm trying to say.
Anyway, it's been fantastic to hear from you all. I feel so lucky to have joined this site.
