I've read that for most people, the right breast is slightly bigger than the left. However, it seems like my left breast is bigger than the right... Is that normal? Also, in both my breasts, there is like something hard in it... Is it a part of growing up? I'm only 13 and i play tennis,badminton,frisbee,cycling,soccer,swimming and many more sports. I do hope the things in my breasts are not cancer...
It is completely normal to have one boob bigger than the other. For most women the right is bigger but there is nothing wrong with the left being bigger. Now for the something hard it would be easier to tell you if u gave more detail. Since u saiid its in both I doubt its cancer. If its in the same. Spot in both it could be muscle, a gland, or even bone you are feeling. So don't worry about it. But if its painful go to a doctor. I have a lump in my breast that wasn't cancerous. It was nothing more than a hard water pocket. So if its bothering you, next time you get a physical ask them to check It. They would be happy to do so. I hope this helps
