How small can I reduce my breasts?
You are talking about 2 different procedures. A breast reduction will reduce the size of your breast leaving a normal appearing, though smaller, breast. One can make the new breast almost any size, though it is much easier to make you a B or C cup. To totally make you "flat chested," is a mastectomy. This is done frequently for males with breast development. It could, theoretically, be done for you. However, I, and most other plastic surgeons I know, would require a psychological evaluation before scheduling this procedure.
