i found a lump a few months ago, my obgyn agreed and sent me for a mammogram and ultrasound. both came back negative but i was told there was "an issue of concern" and had to go for another clinical exam. they are now referring me to a specialist is breast surgery. the question is i found this lump a while ago it does not hurt it has not changed in size or went away at all. i also have since about the same time had some itchy excema-like patches on my left nipple. and the other day i noticed that the left nipple was turning white. it was not like this before. is this something i am overexagerating with or do i have reason to be concerned.
