I have a small,red raised bump on side of breast,it is actually red,elevated skin. It is not a pimple,boil or rash. IT is small.Does it sound like a dermo type problem? I called my gynos' office,have alot of confidence in them,the nurse says it sounds like an age spot or skin tag type thing like she had.Breast cancer does not cause a "red bump" does it? Thank you
