I have it and live with it, although you would be hard pressed to tell unless the angle is right and the environment is warm. 
 
Prone from childhood, although deca is the root of my current problems. 
 
Letro is great and reduced the lumps nearly all the way initially. 
 
Further perseverance with Deca and NPP have made it slightly worse but letro and low body fat keeps things looking normalish. 
 
Will definitely go and have the glands removed when timing and finances are right.
 
Until then all I have is a slightly droopy nipple in the hot and a predisposition for fat storage in the area, which is strange as I am normally very lean and good at dropping bodyfat to low levels. 
 
Also have a small amount of pronounced lumpiness under the nipple as well as the affinity for fat storage in the area.
