Hi @Grandma , although I am not a grandma yet, I am turning 66 middle of this year. I am pleased you posted your comment, as I have similar feelings. Each year in January I have my yearly mammogram and ultrasound and at that time I have severe anxiety, and wonder if I should have just had a bilateral mastectomy when I was diagnosed end on 2016 (cancer in both breasts and in 2 lymph nodes). Of course, I know this would not mean that the cancer could not return, but at least the mammograms and ultrasounds would have come to a close.
I don't know what the answer is, but I do know that each January when I need to have my yearly reviews, I think I should have just had both breasts off in the first instance.
I don't think you are nuts! At times I think my breasts are just time bombs, and perhaps I should have had a bilateral mastectomy, so I certainly understand the dilemma you are going through. A bilateral mastectomy wasn't necessary in my case, so I opted for the bilateral breast conserving surgery, as I was told that most "fare" better ":psychologically" without the ordeal of mastectomies.
Whether we keep our breasts or not is the question!
Some say we should follow our gut instincts, which I did, but , like you I now question my decision.
