I just found out I have fibroadenoma?

I cannot help you much with those questions, but i can tel you that my doctor found it was a better idea to remove it rather than let it be a problem later on. I just got a fibroadenoma removed less than a week ago, and i would definitely encourage you get it removed, since yours is "huge." If you allow it to get any bigger, it could change your breast size or shape. Good luck. Oh, and yes, my surgeon said it is very related to hormones!
