Breast reduction

I'm 18, and I wear a 32G bra. My breasts are an annoying part of my life, and cause more trouble than they are worth. I already have back issues, and they're not helping. Because I have a slipped disc in my lower back, I am eligible for a breast reduction that my insurance will cover. However, I'm unsure whether or not I should do it. I'm young, and I still have time to work on my back. Not only that, but I am worried that someday when I have kids I won't be able to breast feed because of the surgery. What should I do?
