About the possibility of cancer diagnostic by analysis of isotopic content of hydrogen in human fluids

Full text: Cancer diagnostic is one of the main problems of clinical oncology. We report some results on D/H ratio analysis of urine tests of cancerous patients and healthy humans and discuss the possibility of cancer diagnosis by analysis of isotopic content of hydrogen in human fluids. The urine of healthy humans is enriched in deuterium (-60) - (-82) 0/00 in comparison with the average deuterium content in drinking water of Moscow region (-8) - (-89) 0/00. Our data are in accordance with the previous results, but the difference was much less. The water deuterium content of urine tests of patients with different cancer diseases is depleted in deuterium (-85) - (-96) 0/00 and is diminished or close to the average deuterium content of local drinking water. The analysis of our results and their comparison with other data allowed to make a supposition about accumulation of deuterium in a neoplasm tissue, that produces the depletion in deuterium of human fluids. In that case antineoplastic properties of deuterium depleted water (DDW) can speak about the change of moving direction of deuterium in a human organism. Really, the decrease in deuterium content in human fluids, by replacement of drinking water with DDW, should naturally lead to its diminution in a tumor. (authors)
