My doctor will transfer about 100ml fat from my stomach to my breast. Will this much fat removal make my stomach look thin?

Fat grafting to the breastsFat grafting to the breasts give somewhat unpredictable results. It will
not give one a significant increase in cup size. This technique is used
primarily to fine tune the breast contour, or correct some post surgery
irregularly. In your particular case, 100 cc of fat transfer will neither give
you a flat stomach, nor give you noticeable increase in breast size. Typically
in liposuction of abdomen we remove between 500-1,000 cc. Also, for noticeable
increase in breast size, you would need at least 200 cc per breast.

100 cc from your tummy won't make much of a difference. I would be surprised of that is how little your plastic surgeon is removing. I typically remove more than 1000 cc from the tummy and place at least 300 cc or more into each breast. This amount will usually increase your breast one cup.

It's a small amount of fat. I doubt you'll notice much of a difference unless you are quite slender. Best,
