It found a way to identify lung cancer in composition of exhaled air
Diagnostic and preventive medicine is perhaps one of the most important areas. Indeed, any disease is much more amenable to therapy, if detected early. This is especially true of such terrible diseases as cancer. But there is one problem: as a rule, can not recognize the tumor processes already at the moment of the formation of a sufficiently large lesion area, and tests to detect the disease in its early stages are rather expensive. But recently, a group of Russian researchers have managed to create a device that is able to detect the presence of lung cancer is only on the composition of the exhaled air.
For the development of the device meets the Russian Foundation for Advanced Research (BAR). respiratory analyzer allows to detect breath very low concentrations of certain substances that may indicate the presence of tumors, such as, for example, decomposition products of tissue. That lung cancer was not chosen by chance: the fact that it is, first of all, one of the most life-threatening conditions, and secondly, it is lung cancer often recognize only at a late stage. As stated in the report DRF
"In the development of new approaches to the diagnosis of cancer in the early stages of their development have been carried out preliminary tests for the purpose of screening for lung cancer by exhaled air. For this purpose, designed by one of the projects of hardware and software system for detection of low concentrations in the air of a number of substances. We have already conducted a number of tests on animals, the results of which showed prospects of development of diagnostic complex. Our complex consists of both the olfactory analyzer, as well as from the extensive neural network, which allows for fast and accurate analysis. "
