Oxygen – key to most life – decelerates many cancer tumors when combined with radiation therapy
In research examining tissue oxygenation levels and predicting radiation response, UT Southwestern scientists led by Dr. Ralph Mason reported in the June 27 online issue of Magnetic Resonance in Medicine that countering hypoxic and aggressive tumors with an "oxygen challenge" — inhaling oxygen while monitoring tumor response — coincides with a greater delay in tumor growth in an irradiated animal model…
