(ELF) electromagnetic waves (EMW) at resonance frequency with the bio-impulses generated from specific metabolic process will be discussed. The inhibiting frequency of ELF-EMW impulses to Ehrlich tumor growth and in this talk, the basic interaction mechanisms of extremely low frequency implanted intramuscularly the thigh of mice was investigated and found to be at 4.5 Hz. The studies were carried out by different modes 0f ELF namely, amplitude modulated waves (AMW), positive electric or magnetic impulses at the same frequency. Experimental data indicated the inhibition of tumor growth and highly significant improvement of survival period of the ELF treated animals relative to control. The studies were expanded to study the effects of whole body exposures of tumor implanted animals to 4.5Hz EMF on preventing metastasis in liver, kidney and spleen. Histological examinations and dielectric relaxation studies for these organs indicated that treatment by EMW caused a decrease in the percentage of metastasis in the studied organs and loss of animals as compared with untreated groups. It was concluded that exposures of animals injected with Ehrlich tumor to 4.5 Hz EMW can inhibit tumor growth in secondary sites or distant organs and can be used as preventing agent to murine metastatic development.
