For 3 months now I have had an itching from inside my left breast radiating out and towards the nipple. I also around the same time noticed a white spot on the tip of the nipple. It looks white/cream in color. I have never had any discharge from the spot, but it continues to remain there. It kind of looks like a milky duct, but again, it has never leaded. I feel no lump in the area. In dec I had a mammagram and it was normal. I did mention this to the tech at the time but she never looked at it, just said it was normal to have discharge...which I am not having. Is this something I should be concerned with or it is a common thing for women in there late 40's. (I am 48)
