I was prescribed a cream by the radiologist to apply before every radiation. Never had any skin problem throughout radiation.
For me calendula cream did the job
I used aquaphor as directed by my doctor. I came out with intact skin.
Good luck!
Dermavitality Radiation Relief Cream & Spray was recommended to me, and they also have products for Chemo developed by an Oncologist. I purchased in preparation for radiation, which I ended up not needing, but use the cream and love it. I have a friend going through radiation and she said it was so good and she never had any skin issues.
I had a mastectomy as well but micro metastases in lymph nodes on the left so that is why I still got radiation. I forgot about Emu oil will look for it. Thanks
