16 years old - Do I have tubular breasts?

Thank you for your photo and question.Yes, you have the classic appearance of moderate tuberous breasts.You have many options to correct and enhance your breasts.Since you are a minor you will need to bring one or both of your parents with you for a consult. Make sure your Plastic Surgeon is a Bd. Cert. Plastic Surgeon and ideally a Member of the Am. Soc. for Aesthestic Plastic Surgery  (denoting have mey additional levels of achiement and experience in Cosmetic Plastic Surgery).My best wishes, 

You have tubular breasts without a doubt!The three classic signs include: herniation of breast tissue into the nipple-areolar complex, poorly defined infra mammary fold, and lack of breast tissue along lower part of the breast. The reconstruction will include implants with release of the lower pole radially and possibly reducing areolar size .

Yes you do indeed  have tubular breasts.  They may not have stopped growing yet.  You might want to discuss your concern with your parents and consider a consult with a plastic surgeon.
