I had radiation 4 years ago. Finished 11 Nov 2013. I was told that it is always worse for those of us who have had a mastectomy. My skin held up very well and only reddened in the final week. But the reaction worsened (as I was warned it could) after radiation came to an end.
My skin under the arm and on the chest turned black and flaked off. It was very moist looking but I was told this was because I had kept it well moisturised during radiation. Underneath the skin was pink and healthier looking but it was a month before I could wear my bra and a soft prosthesis comfortably. I remember being so frustrated and upset because treatment was finally over but I was stuck inside unable to wear a bra etc. I used pure Aloe Vera and my skin healed really well in time to enjoy Christmas and even swimming again.
At this stage the damage is done and it is just a matter of time. I found just keeping it moist seemed to be all I could do until the damaged skin finished coming off. Everyone kept telling me once it started to heal it would heal quickly. They were right but I was still terribly upset and just wanted it to be over so I could start to move forward again. It is a very difficult time. Wishing you a speedy recovery. xxx
