I had to have one back in the 80's. Results were good for me and the after surgery pain... well, I was back at work the next day. There was no pain.

I have/had that Fibrocystic Disease also so they watched my breasts very close because of all the lumps and soreness that brings. Year before last I had to go back after my mammogram because there was something questionable there but after ultrasounds and other tests, they just decided to watch it... It didn't even show up on last years.
