Although there is no dire medical necessity to perform gynecomastia surgery urgently, I would recommend you perform this surgery sooner rather than later.  The reason why early gynecomastia is to your benefit is that the increased soft tissue fullness can stretch out your breast when left untreated. The problem with stretching out your skin is that it will result in you potentially needing a skin reduction as well. Early removal of soft tissue fullness will result in you not needing more extensive skin reduction surgery.
