[Analytical epidemiology of osteogenic sarcoma in the Armenian SSR].

Morbidity rates for osteogenic sarcoma in the Armenian SSR within 10 years (1970-1979) were studied. The climatic, geographic and geochemical peculiarities of low and high morbidity rate regions of the Republic were compared. The rates were high in areas where the soil is rich in boron and poor in silicon, cobalt and zinc and where, as a rule, calcium level in irrigating and drinking water is high.
