I have developed fat necrosis following DIEPs Flap surgery then radiation, how can I address this?

I had a double mastectomy and DIEPs Flap surgery in Nov. 2015. The cancer was worse than originally thought so I then had chemo and six weeks of radiation. I have developed fat necrosis in the breast that was radiated in the chest area (above the breast). Will this go away or at least soften? Is there anything I can do about it, other than surgery?
