When should chest fat grafting be performed?

Actually, I never considered chest fat grafting, but in what situations should I consider and absolutely undergo fat grafting? How much does it cost? Since it should be done at a reputable and well-known plastic surgery clinic, is the success rate high? Is the success rate 100%??

Are there any precautions or considerations to keep in mind without side effects for how long after chest fat grafting should I be cautious?
