Are there any alternatives to a saline or silicone implant for breast augmentation?

Fat grafting can be used for breast augmentation.  It will require you to have fat to donate from another area on your body and you may need multiple fat transfers to achieve your desired results.

Fat grafting is still in its infancy.  I doubt you will get a meaningful change with fat, assuming you have enough to harvest.  Has your husband felt silicone implants?  He may have a skewed perception of what is out there! I feel like most women (and their husbands) and very happy from silicone implants!  Take your husband with you to consult with a BCPS and that should help!
