Can there be any way to increase breast size without surgery?

Weight gain: Besides pregnancy and weight gain there are no non-surgical alternatives to enlarging your breasts at home.

Only surgery: The only proven reliable method that is permanent is surgery - either with implants or fat transfer. There are no creams, pills, exercises or other methods that have been proven to work.

Breast augmentation: There is no medication that will make the breasts larger. Breast augmentation is a cosmetic procedure using a silicone or saline implant to achieve the desired size. One relatively new option (and somewhat controversial) is using a device called brava for a period of time followed by transfer of fat from one area of your body to the breast during surgery. This option avoids the implant.
