Hi, I have had lumps in my breast for a while now, like years. My right breast will swell and go back down but I have almost a rocklike lump. My breast are so sensitive almost to the point where I can't wear a bra. Not that I need one anyway. I'm 16, 135 lbs, and I still wear a 34b. But like I said the one on the right keeps swelling but it's not growth cause it goes back down. I'm just scared. I've read that it's very unlikely for a 16 year old to have bc but IT IS POSSIBLE! Please do not tell me that there is only a slight chance cause with my luck i would be that 1 to have it! For the ones who have been through this please help me. I haven't told my mom. They hurt so much! I can't even sleep on my stomach. This lump has never gotten this bad and it just makes me nervous! Thanks!
