[Trace element content in the blood and tissues of patients with precancerous and precursor diseases of the female genitalia].

Emission spectrum analysis was used for measuring the levels of such trace elements as copper, manganese, zinc, nickel and silver in blood serum and tissues of the diseased organs in female patients with certain precancerous and precursor lesions of genital tract. It was found that such changes as an increase in serum copper, a decrease in zinc concentration in blood cells and a rise in the levels of zinc and silver in the affected tissues were more pronounced in cases of precancerous lesions than in those of precursor pathology.
