I am 5 foot tall, 107 pounds and wear a 32/30 F. I am 19 so hopefully they will not get any larger. I was wondering how much weight I would have to lose to go down a few cup sizes. My back has recently started hurting but I'm not sure if I damaged it as a gymnast or if I can blame my cup size. I think that my large breasts are ruining my quality of life and have taken away my confidence. Is reduction surgery the only way to reduce size significantly?
