I'm 20 years old, and my boobs are small even smaller than a 13 years old girl. What happened with me?

Thank you for your question.  Nothing "happened" with you: Your anatomy is a result of genetics.  If you are wanting to increase the size of your breasts, you should consider having implants.All the best,Dr. ResultsMiami, FL

Thank you for your question about breast implants.I am not able to give you any meaningful information without at least photos.To know your situation, see two or more board-certified plastic surgeons in your area for a full and complete evaluation to make sure you are a good candidate and that it is safe for you to have surgery.I hope this helps.

Hello, there is a wide range of normal breast size, so you many have normal development.  However, some people have a disorder that results in decreased breast size.  Your physician may be able to give more specific insight in your case.

Thank you for your question, and I am sorry that your breast size is causing you concern.  Much like height or hair color, there is a wide spectrum of breast size and shape in the human population that is largely determined by our genetic material.  If you are interested in pursuing a larger breast size a breast augmentation with the use of implants may be a possible option. See a board certified plastic surgeon who can discuss with you the pros and cons of such a procedure. 

Some women are just born with smaller breasts.  A breast augmentation should help.  Please seek a board certified plastic surgeon for a consultation.
