Itchy Breasts.

My Breasts Has Beem Itching An Awful Lot Lately. I Don't Know What The Problem Is.. I Haven't Changed Soaps And I Use Lotion ,Cause I Figure They Are Dry? I'm Kinda Getting Worried Because This Has Been Going On For Weeks. It Can't Be My Bra Either Because I've Had Them For Sometime Now I Don't Know What To Do And Google Isn't Helping All I Keep Seeing Is Breast Cancer. Any Nurses Can Help Me? Thanks In Advance.
