Okay, so, I've had this mole right on the side of my right breast for about 3 or months, and I haven't really paid it any mind until earlier when I looked in the mirror and noticed a small, red splotch resembling almost a poison ivy-ish patch originating from the side of the mole and spreading out about a 1/2 inch further. It only started itching recently. Is this a concern, and can someone tell me what it might possibly be?
