Should I get fat graft breast augmentation or implants?

My natural breasts were a small A cup. I had large saline implants over the muscle when I was 23 years old. It was a bad look, visible with ripples. At 33 years old I had them removed and replaced with smaller silicone implants under the muscle due to capsular contracture and hardening. Now I am 40 years old and had explantation two weeks ago again due to hardening and capsular contracture and I am still dealing with blood build up in breasts that needs to be extracted. My skin is very thin and I have a very small amount of breast tissue left. At present I also have a scar under the areola inverted in a fold and general deformity. I think fat graft may help build breast tissue back up and help with lifting out the inverted fold. I don't care about the size. I just want to look normal with small natural breasts again. I've found a plastic surgeon that doe s this procedure often and has purportedly a 70-80% fat sticking success rate. I'm afraid of continual hardening with implants and possibly eventually having the implants come through the skin due to it being so thin already. Please advise - am I barking up the wrong tree with fat grafting? I need to act fast before inverted folds tether down to the muscle permanently. I am aware of fatty cysts but read online that good mammogram technicians/readers can detect the difference between benign cysts and malignant tumors (they can detect fat cysts that are not be be worried about). Please help me as I need more information.
