Hi, I'm 15 and a couple of days ago in the shower I noticed that on my left breast close to the nipple there was a slightly red hard and sore spot, it was a small spot at first and I didn't think to much of it, but now it seems as though the spot is moving around the outside of the nipple and it's slightly warm to the touch. I haven't asked my mom or sisters about this yet, I wanted to first get a little feedback. Please help me, I really am scared it's something like breast cancer.
