Extremely underdeveloped breasts. Is it normal?

Your breasts appear to not be affected by any abnormality, and if you are getting your period consistently, then I don't think you should be worried about being "underdeveloped". You may just have small breasts. However, you should talk to your GP to find out if there are any issues. Your breasts will continue to develop as you age, and you may find that you experience dramatic growth by 19-20 years old.

Thank you for your question.  Although your breasts are small you are very fortunate that there is no significant developmental abnormality.  By this I mean you do not have a tuberous breast which is very difficult to correct.You simply have small breasts with minimal breast gland development.  You are still young and your breasts may enlarge over the next 2-3 years.I would urge you to wait until you're 22 before deciding to have breast augmentation surgery.  Your development should be complete by thin and at that age you will be able to have silicone gel breast implants.  I understand how difficult it is but I would encourage you to be patient and wait.For more information on breast augmentation please read the following link:

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!
