I am fifteen years old, and I have a lump on one of my breasts. I think I've had it for about almost a year? It feels sort of circular if I press onto it. Also, sometimes a clear fluid comes out of my breasts, and I know for sure I'm not pregnant. Not only that, but I have been experiencing some hair loss as well. I'm scared I might have something wrong with me. Can you please help clarify what's going on? I'd really appreciate it ...
