My son is 9 years old. He is in perfect health, very athletic, just your typical boy. However, recently we have noticed that his sternum has sort of an "outward" growth to it. It is like the opposite of a "sunken chest', it is kind of like a "bulging chest". If you know what this may be or if it needs any treatment please let me know.
