I am half way through the radiotherapy treatment to my breast and have some eruptions beginning to show on the skin above my breast itself. The radiotherapy nurse told me it was radio dermatitis and that I should not put anything on it for now as it is a reaction to the radiotherapy and oils / creams / aloe vera might cause an allergic reaction and, should they contain metals (I don't use anything with metals), cause an adverse interaction with the radiotherapy. It seems strange to me to wait until the skin is really inflamed to do anything about it... I would like to apply organic calendula and aloe vera. Any comments?
