First of all, your term uni-boob is not applicable to your situation. It is probably not important what you call your breasts. The important issue is to define what exactly bothers you (size, shape, cleavage, sagging, symmetry???) and even more importantly, what will make you happy. Once this is understood by your surgeon, and after a complete physical exam, treatment recommendations can be suggested. The fact that you had this since puberty, and assuming you are not obese, you might have juvenile macromastia. Consult with your gynecologist or family doctor about other causes of mammary hypertrophy. A breast reduction might be contemplated if medical causes have been ruled out.Robin T.W. Yuan, M.D.
