First of all, though fat grafting has been embraced by a number of unscrupulous, self-proclaimed "cosmetic surgeons," as well as a few reputable ABPS-certified "real" plastic surgeons who feel they are performing a legitimate procedure with few risks, MOST ABPS-certified plastic surgeons with years of experience (with implants of all kinds AND fat grafting procedures in other parts of the body) do not recommend fat grafting for breast augmentation.
This is because no matter how good the surgeon's technique is and how carefully the fat is harvested and transplanted, SOME of the fat cells die and cause scarring (and sometimes calcifications) within the breast. This can interfere with the detection of breast cancer! Those of us ABPS-certified plastic surgeons who are also fully trained in General Surgery have done plenty of breast operations for cancer, and later (as plastic surgeons) for breast reconstruction, so this is not a "minor issue." 11% of women develop breast cancer at some point in their lifetime.
Herbs, exercises, creams, and any kind of pseudo-pharmaceutical remedies only benefit the seller. Do not waste your time or money.
Two cup sizes is a fair amount of breast volume increase, even for those who DO espouse fat grafting for breast enlargement. Silicone (latest generation of cohesive gel implants that cannot leak) is truly the way to go. Click and read the web reference link below for more information about implants.
BTW, if you had cancer and needed chemotherapy, did you know the tubing that is inserted into your body for delivery of the medication is silicone? If your heart needed a pacemaker, did you know the leads inside your heart and blood vessels are insulated with silicone? If you were diabetic would you refuse insulin because the needles are lubricated with liquid silicone? Breast implants are made of the same polydimethylsiloxane polymer as these and a myriad of products, so the "scare" information you are concerned about really does not apply, even if you have sensitivities to many things. Silicone is extraordinarily unlikely to be one of them. Yet it is hard to convince someone of the science rather than the "junk science." Do not proceed with anything unless you are sure of your facts! Best wishes! Dr. Tholen
