Just got back from the surgeon's appointment. Everything is fine. Basically the bump is either a tiny cyst or dense breast tissue that has become a bump. It's probably a cyst though because of the fact that it has gone down in size.
I did notice a small pink splotch, about the size of a pencil eraser head, on the side of my left breast. I first noticed it last night. It doesn't itch or anything, and it's not raised. I asked him about it and he didn't seem concerned and it's most likely just irritated skin. But I'll just keep an eye on it. It's probably from me poking and prodding myself and irritating the skin. =_=
