I am a 28 year old, 6', 164 pound caucasian woman with no known health issues. I've developed two small, light brown blemishes on the side of my left breast. They're flat and smooth, cause no discomfort/itching, and there are no lumps. They're both about 1/4 of an inch around, with two inches between. I have very pale skin and freckle easily, but that part of my body isn't often exposed to sun. Advice greatly appreciated!
