Hello and thank you for your excellent question. There is no direct correlation between grams of reduction and breast cup size, in particular because bras are all fitted differently, and because breast tissue can be removed from different areas with different results. It is essential that you have an in-person consultation to develop a treatment plan that specifically addresses your personal surgical goals, and your body’s anatomy. I recommend that you find a board-certified, or board-eligible plastic surgeon with whom you are comfortable. Be sure to have all of your questions answered during a face-to-face meeting with your surgeon, and review before and after pictures of similar patients whom have had this procedure. If you have any questions, call our office for assistance. Good luck! Best, Jon Ver Halen, MD FACS Harvard educated plastic surgeon Texas “Top Doc”
