The nurse only responds once to a question. You might see a dermatologist though, breast cancer does not always itch, hurt, etc. I felt nothing with mine, just found it with a mammogram.
sorry i should have stressed it is NOT on the skin it comes from the inside underneath the skin, no rash no open skin no dry skin etc.
Dear sheep: Skin on the breast is like skin anywhere on the body and is subject to a variety of abnormalities. Without examination, it is impossible to speculate on a possible cause. You should see your doctor (or perhaps a dermatologist) for examination.
