I have itchy breast. The problem started about 2 weeks ago. I haven't changed detergent or soap. I have been wearing the same bra for months. I had a routine mammogram in January and 3 (5mm) cyst were found in my right breast. My mom is a BC survivor. Should I be concerned? I have tried hydrocortisone cream, benadryl, pretty much every thing I can think of. I am open to suggestions at this point. I'm tired of itching!!!
