Double or single?

I chose a bilateral as I had high family risks..but I now know do not have an identifiable gene. But my cancer wasn't picked up in a mammogram 5 weeks before I foubd a lump due to breast density. For my own piece of mine and at the suggestion of the surgeon I underwent a skin sparing mastectomy with tissue expander reconstruction. I will go for changeover in a month. So far happy with the result. I guess the thing to think about is the loss of real breast sensation...regardless of procedure. I've adjusted..but it is a big change and sonething to ponder.
