Radiation burn on areola - how to fix texture and color from radiation?

Last year I had radiation on my breast after I had a lumpectomy for breast cancer. The breast in general is fully healed a year later, but the nipple is discolored (a yellow-brown color) and the texture is a bit different from the non-treated nipple. Are there treatments that can be done to help improve the color and texture of the areola? I'm a 50 year old woman, and now in good health. I've been using scar cream on my scars and areola, but wondered if there is anything I can do?
