I would recommend that you get seen by a breast surgeon and  endocrinologist to confirm the nature of this swelling and maybe do some blood tests/xrays, then procede according to this.
good luck

There will probably not be any problem.

I was a USAF Medic (1955-63).

While there, I observed that a whole lot of guys have gynecomastia.  You are much more normal than you think.  If you really look, almost 2/3 of all men have it to some degree.  

It is also very common for the breasts to be of different size.
