Although these medications are approved by the Food and Drug Administration, they have not been approved specifically for this use. you still have significant bothersome breast enlargement despite initial treatment or observation, your doctor may advise surgery. Two gynecomastia surgery options are:
Liposuction. This surgery removes breast fat, but not the breast gland tissue itself.
