Rare Breast Cancer Types

Itchy rash around the nipple?
Recently I started having this itchy rash around my nipple left. I've been trying to search online but did not get exactly what you want. In any case began two weeks ago and at first was a rash is a bit sensitive to touch, then began to hurt a little, and as a day or two I noticed a small rash around my nipple. Both sorta chest hurt, but is left w / the eruption and the most pain. What could this be? When I looked for the eruption of the nipple mention a rare type of cancer a couple of times but have most of the other symptoms except the rash and I have no downloads. It has never been Preggy so any thinking about it or anywhere I go? I know you probly need to receive a check for my doc …
My best estimate would be an allergy to something in their clothes. Have you recently changed detergents or buy a new shirt / Bra, which can irritate your skin?
