Hi, Is the Gynecomastia affecting one or both breasts? What is your weight? If you want to avoid surgery, the only thing you can do is to loose some weight till you reach less than ideal weight for your body as per standard weight charts. The only other treatment would be liposuction which is a minimal access surgery done by Plastic surgeons in which they suck out the underlying fat through a very small incision. There are some medicines which lead to Gynecomastia, so please ensure you are not taking any of the medicines that lead to this problem as a side effect. You can get the list on Internet. Take care.
