At 16, your breast development may not be complete, and your changing height, weight, slacks size, and bra size are all indicators that can help you know if there is growth that may yet occur. Let's hope there is, and your breasts will grow more. Even when all growth is complete, you may still be smaller than you desire, and breast augmentation is the operation you may wish to consider.And if growth is complete right now, then there's breast augmentation to consider. So you're covered either way. For now I would recommend educating yourself about breast augmentation, and avoid creams, pills, exercisers, or even Brava devices. (Brava can give 1/2 to just under a cup of breast enlargement, but the growth is not long-term, and the time, money, and effort expended is NOT worth it, IMHO.) The rest are worthless.Fat grafting remains controversial, but in my opinion has no place in normal breasts, since some of the grafted fat ALWAYS dies, causing scar lumps and potential calcifications that can cloud the detection of breast cancer via physical examination or mammography. Since (even with tiny breasts) you have a 1 in 8 or 9 chance of developing breast cancer in your lifetime, early detection is a big deal. In my opinion, fat grafting into a normal breast for enlargement is NOT "natural" and NOT advisable.BTW, your breasts are not abnormally shaped--they're just small and somewhat widely spaced. You are a great candidate for breast augmentation, but would need parental consent before age 18 (and it isn't advisable until the growth question is definitively answered in a year or three). For more information, click on the web reference link below for my Comprehensive Guide to Breast Augmentation. You can even ask your mom to read it (and dad too if he's cool with that) so they can become your advocates rather than your roadblock.In the meantime, you should also consider asking your parents about a gynecology or endocrinology consultation to have your hormone levels checked, just to be thorough and complete. Wouldn't it surprise everyone (even you) if you would benefit from bio-identical hormone supplement(s)? Asking for a "female physical" shouldn't be met with too much resistance, especially if you have the courage to ask them in a serious fashion. They'll be glad that you're not asking them about pregnancy or STDs! I'm taking you very seriously, and those who aren't are obviously NOT the ones to be asking. Something may not be wrong, but you shouldn't be afraid to ask the very reasonable question. Get going and talk to your parents, or start with the parent you feel you can talk to the most comfortably (might even be your dad). Good luck and best wishes!
