I'm curious about breast fat grafting.

I have a few questions about chest fat grafting surgery.

First, I am curious about how much it will cost.

Which is more expensive, implant surgery or fat grafting surgery?

And if you go on a diet after fat grafting, is there a possibility that the operated breast might also lose volume?

Finally, if you were to recommend, would a prosthetic surgery be better or would autologous fat grafting surgery be better?
