I am a 41 yof, w a 2-3 mo. Hx of bilateral Breast discoloration. It appears as bruise like, irregular patterns on both breasts. There is no retraction of the nipple, or skin dimpling, or discharge. I had a normal MMG August last year. There is no pain, and no obvious lump or bumps. I am less concerned because it is Bilateral, and had a normal MMG last year. However, it is not going away, and I have no idea why it appeared.
