Radiation Newbie

I specifically got told to stop my vit e and c tablets because it interferes with what radiation does. I also got told not to use sorbolene that had glycerine or vit e added. They suggested aqueous cream. I have been using an organic rosehip oil on my scar which has healed well. I'm mixing some in with the aqueous cream. The rosehip was suggested to me by a naturopath at a chemist when I had a hysterectomy. He said avoid bio oil as it has petrochemicals. Also some pawpaw may not be that good if it has additives.
