I appreciate your question
I perform a natural breast augmentation with fat. This can be removed from any unwanted areas including the breast itself as part of my lipo-lift procedure. I perform the fat grafting in multiple planes including under the muscle to give the best, most natural enhancement. Fat grafting is a great solution for someone who wants to bring their breast size up a cup or so and use natural tissue vs an implant. However, it can also be combined with an implant or used as a secondary procedure to fill in areas that are flat or thin. It should not affect nipple sensation, mammograms or breast feeding. It can be a little lump or hard at first but tends to soften over time.
Fat embolism can happen
The best way to assess and give true advice would be an in-person exam. Please see a board-certified plastic surgeon that specializes in aesthetic breast plastic surgery.
Best of luck!
