Claims (2)

1. A method for diagnosing cancer, including testing organs with known physical methods, examining a suspected tissue by exciting it with a beam of monochromatic light to produce a fluorescence spectrum and comparing it with a similar spectrum of normal tissue followed by computer processing of research results, characterized in that carry out the study of normal tissue of the same organ by exciting it with a beam of monochromatic light and following excitation with a beam of polychromatic light in a wavelength range of 400 - 800 nm to obtain the reflection spectrum, and in the investigation of suspected tissue to produce fluorescence spectra excited with a beam of polychromatic light to obtain a reflection spectrum, which is compared with a similar spectrum of normal tissue; the condition of the suspected tissue is judged by the ratio

where I _max - the intensity of the maximum of the spectrum line in the region of 590 - 605 nm;
1 (578) is the intensity of the minimum of the spectrum line at the point 578 nm, corresponding to the peak of blood absorption;
I _maxn , 1 (578) _n - for normal tissue;
I _maxc , 1 (578) _c - for the suspected tissue,
moreover, when q _~ 0-, normal tissue is diagnosed, and when go <g <O, the presence of oncological disease with specification of the type of tumors by q value.  2. A device for diagnosing cancer diseases, consisting of a source of light radiation, an optical communication unit, a radiation supply and acquisition system, a spectrum analyzer and a computer, characterized in that it contains an additional radiation source, and the radiation delivery and acquisition system is mounted with a single medical needle having inside monofilament hard fiber.
