I am a small guy so I know I am not overweight, I had it sense I was13, the day I hit puberty and I am now 19 going to be 20. I am not sure if it has gotten smaller sense then, but it is not that big to begin with but it is noticeable if i wear the right shirt. I not sure if it has something to do with a tumor in my kidney? or Hormone inbalance, because my mother has alot of estrogen in here, so I wonder if I develop that from her? What should I do? I like doing things naturally/organic. Is there something I can enhance in my diet or avoid?

The best thing to do is to consult your doctor. Sometimes losing weight will reduce breast size. Sometimes the only option is to live with it or get a male breast reduction. Might be good to determine if it is a horomone imbalance so you can get some horomone shots if you need it.
