Microwaves in radiotherapy of tumors - alternative to heavy particles?

An increase of the radiosensitivity can be obtained by means of microwave use in combination with sparsely ionizing radiation. Comparing the therapeutic effect on the model of an euoxic tumor (mice testicles) with a tumor that contains important parts of hypoxic cells (solid tumor of Ehrlich) it appears that the sensitization evidentely is seen in the hypoxic tumor first of all. No sensitization can be obtained on the euoxic profileration tissue on the testicles.
