What makes you have a reconstruction?

I had a bilateral tissue sparing mastectomy and immediate reconstruction done with tissue expanders. I originally was interested in a flap reconstruction but after discussion with my surgeon and decision of a bilateral an implant reconstruction was a lesser surgery, could be done by my breast surgeon and not only by a plastic surgeon and could be done in 20 days. Any other choice would have meant a delay whilst new referral to plastic surgeon and surgery wait. For me having it done at the beginning was very important. Aesthetically it can be a better outcome if planned from the beginning (but not necessarily) and it didn't mean having to cope with 2 prosthesis whilst I awaited surgery. Whilst I had private surgery I chose public as I felt the gap expense too high. In my mind I always thought if really unhappy with my implant reconstructions I could still revisit a flap reconstruction at a later date. I am thus far very happy with the outcome. The changeover surgery was very minor so the need for replacement at 10 to 20 years doesn't concern me.
