I'm a 34b & I would like to be 34c, so how much would it cost me to have fat transferred from my abdomen & arms to my breast?

Generally there is a cost for the liposuction procedure and a separate one for the fat transfer procedure.It is important to realize that liposuction or liposculpture is best to contour areas of the body that have a disproportionate amount of fat.  It is not a good procedure for weight loss.  Liposcutioning is best performed when patient is near their goal weight to address area that are resilient to weight loss.  Please obtain
a consultation with a plastic surgeon to determine if you are a good candidate
for the procedure.

Both other answers were very good advice. The real question is are you willing to have 2 or possibly 3 operations to obtain a stable, final breast volume ---all in order to avoid an implant? Some people are willing to go through this, others aren't. If you haven't been advised that several operations would most likely be required to achieve your desired results, or you just assumed it could all be done in a single operation, then dispelling the myths and getting accurate information is the first step.   Accurate, reliable, safe breast volume increase can be obtained in a single operation using breast implants. So if you are trying to avoid an implant at any cost, then fat grafting is a reasonable alternative. Costs will vary as someone else advised you. You'll have to call individual offices to obtain that information.

I prefer to use implants because I feel that they are more reliable in terms of predicting the overall volume of the breast after treatment. Fat does not take 100%.
