Best to go to a breast reduction expert. Look for lots of pics and check out the web site. I would recommend a board certified plastic surgeon for the best results.
Can he reduce a very large breast?
While breast reduction and breast lift are done through very similar incisions, the technique is usually very different. Your surgeon clearly has very good experience doing breast lifts but if he has disclosed that he usually doesn't do a large reduction, you may have more peace of mind if you directly ask him about his comfort level doing your surgery or even getting another opinion or two. Just because he doesn't do it often doesn't mean he CAN'T do it, but you would be best in the hands of someone who is very comfortable doing this type of surgery. Best of luck!
PS does 100 breast lifts a year. Rarely does large reductions. Can I trust he can reduce a very large bust?
Make sure that your selected plastic surgeon is a board-certified plastic surgeon. If he/she has experience helping patients with larger reductions you should be able to view before/after photographs. Doing so will help you achieve peace of mind. Otherwise, (in my opinion) best to seek additional consultations. Best wishes.
