C to B or A is possible, but will that help you?

If you truly are a C cup, then it would be very unusual to request a breast reduction operation. The back and/or shoulder pain you may be having could be due to breast size or several other conditions that may have nothing to do with your breast size. After a breast reduction, you will have a decrease in volume and a lift in the breast tissue. However, there are patients who have undergone a breast reduction for pain and still have pain after the procedure.

Let a plastic surgeon examine you and determine if you need a reduction. They will also talk to you about how your symptoms might or might not improve after the procedure. Good luck.
