Uneven Breast Growth in Teenagers: Causes & Concerns

Question
Hi, I'm 14 and my boobs are not the same size. My right one is quite a bit smaller than my left one, though it is not that obvious when I wear clothes. I'm a right hander and thus do many things with my right hand, including play netball. Could this have anything to do with the amount of energy I burn on the left side of my body as compared to the right? My muscles are more on the right side of the body. Any advice? Thanks in advance.

Answer
Hi Scarlett.

The netball might be the reason, but it is actually very common for one breast to be larger than the other.  The muscle tissue on your right side could play a role in that though, but I wouldn't worry, you are young and not done growing.  Give it a chance, and if you have this problem when you are 17, go see a doctor.
