All I can say is, I have been through this to and so did one of my friends and we both had fibroadenomas too.. In most instances, breast lumps are benign as someone else has said so try not to worry too much about it at this stage, no use worrying before you have to, although I know how hard it is not to.. Many women have something called fibrocystic breast disease which is lumps that flare up at different stages of the cycle, its quite common.. so hopefully at best its just a blocked duct, and at worst might just be one of those fibro lumps..
