Hi, in most cases of men complaining of appearance of breast, as that in women, there is usually self diagnosis of Gynaecomastia. Men with weight issues may also appear to have this complaint, but your weight seems appropriate for your height.
Next Steps
Meet a physician, homeopath or otherwise and get yourself checked. After physical examination, if required blood tests, ultrasound may be suggested. If found to be a case of Gynaecomastia, either medications or surgeon opinion would be sought
