Is it possible to go from a C cup to an A cup? (Photo)

Thank you for the question.

I am glad that you will be waiting at least 2 years before proceeding with any type of surgery. Based on your description, currently a “C cup",  you not sound like the patient suffering from “juvenile breast hypertrophy”. Waiting at least 2 years will give you time to really think about your goals and the potential risks and complications associated with breast surgery (especially at your age).  I am concerned that, unless you receive wise guidance, you will make mistakes with regards to your breasts  that  you forever regret.

PLEASE BE CAREFUL.

In general, breast reduction is delayed until the patient is fully grown and can sign her own consent form unless the situation is extreme. Normal breast size is up to a C-cup size. An A cup is small normal, B cup is average, and a C cup is bigger normal. Another way to look at it is that the female body/chest is built to handle an A-C cup size breast but not D's or larger which can result in strain on the back and neck. 

After you are fully grown and able to sign your own consent form, a cosmetic procedure such as augmenting the breast to a larger size or decreasing the size to less than average could be considered but enlarging it is simpler, less scar, and more reversible. Reducing a breast from big normal to small normal is not commonly done and certainly would not be done as a functional or medically necessary procedure to relieve symptoms. The situation would have to be assessed and the plastic surgeon would have to use his or her judgment on the reasonableness of such a procedure.
