What Causes Uneven Size Of Pectoral Muscles?

Hi I'm a 19 year old male who's been bodybuilding fairly regularly for about a year. I recently noticed that my left pectoral muscle is considerably smaller than my right pec muscle. Is there a medical reason for this? Is there some way to correct this imbalance?
