Radiation & showers

[lizm100]

Hello everyone-

I need input, recently finished radiation therapy and was trying to find a "natural" sunscreen instead of a regular chemical one. During my search, I discovered that many sunscreens contain Titanium Dioxide which is used to block the UVA/UVB rays from the sun. I also learned that most regular soaps contain Titanium Dioxide such as Dove etc. While doing radiation, I was instructed to use Dove soap. Also, I was told not to use any deodorant on my treatment side so I always took a shower 1-2 hours before my radiation therapy.

Now I'm worried...if the Titanium Dioxide in the Dove soap could have interfered with the effectiveness of radiation? Are the radiation rays used in therapy different from the UVA/UVB the sun gives off? I called the company that makes Dove and the person I spoke with was not very knowledgable, she told me that they used it in the Dove as a colorant but is not sure if has sunscreen properties....she was absolutely no help. I tried to reach my radiation oncologist who I was told was off today....I am going out of my mind with worry!! Any input would be helpfull!!!

Thank you,
Liz
