These are really uncommon occurences in a male breast. These are most commonly benign changes but it is important to rule out other conditions that seems to be causing this breast tissue enlargement in a male. One of these causes are liver problems which can increase your endogenous levels of estrogen, and therefore stimulate breast tissues.
thats for the help the tests that were done showed my liver is working fine. If it was the liver won't both breasts have increased tissue. My doctor stated usually this happens during puberty which I'm to old for and with some medicine. My concern is the pain aspect as the one is very painful even to the smallest touch and seems to be growing towards my underarm.
