I had a person approach me at the gym this morning and ask me about gyno....after we talked for a minute i ask him to let me take a look at his chest.....he has lower chest fat in which i was surprised b/c it was not noticable through his shirt at all.....the fat runs through his lower chest to around under his arm...around his nipple area which extended out about 1/2 inch looked puffy.....there is absolutely no lump and he said there is never no sensitivity or itching.....could this possibly just be fat.... thanks....
