This study is for the patient with breast cancer. To take part in this study, external beam radiation therapy needs to be part of the treatment plan. Reduced glutathione, an ingredient of RayGel™, has been helpful in decreasing some radiation therapy side effects to the skin.

Reduced glutathione plays a vital role in both making DNA and cell repair. This study will measure if RayGel decreases skin reaction in breast cancer patients treated with external beam radiation therapy.
