Looking for a Doctor for Breast Fat Transfer in Europe - Who's best? Please recommend!

I have been researching breast fat transfer & would love to have this procedure done. I have looked at a few docs in the States but wondered if there were any specialists in Europe? I read somewhere that this procedure was originally pioneered in Europe, so why is it so difficult to find a specialist? I thought Germany particularly would have many. I hope I'm a good candidate as I'm slim; 5ft 2' and 122lbs (size 8) with 34A breasts. Lipo ideally fr inner thighs.
