Medications used to treat breast cancer and other conditions, such as tamoxifen and raloxifene may be helpful for some men with gynecomastia...if you still have significant bothersome breast enlargement despite initial treatment or observation, your doctor may advise surgery...consult nearest surgeon they will do the needful.
