The new method of tumor therapy is proposed: joining up proton (photon) and microwave methods. The combined tumor therapy gives the possibility of simultaneous influence on the albumen molecules (tissue cells) in vivo of RF/microwave and proton (photon) radiation. Such an influence must be made not only synchronous but coherent as well. In this case the effectiveness will depend on the relative phase between the proton bunch sequence or photons, radiated tissue and radio frequency oscillations, with the help of which bunches were formed and accelerated in the accelerator. The proposed combined proton + RF/microwave therapy method gives the possibility of simultaneously (with proton or photon) and coherent influence on the tissue cells, in the wide microwave range, included the mm-range. It may be provided by multiplication of the accelerating field frequency by n. It is necessary to mention, that the additional MW therapy is able to decrease the proton (photon) radiation dose for patients, because centers of the devitalisation of tumor tissue may be explored due to MW action (already without proton or photon radiation). The linac of the YerPhI synchrotron at 75MeV, in which it was proposed to establish the proton linear accelerator, at 12MeV, is the likely accelerator for carrying out this method of tumor therapy.
