An integral mark of the epidemiological and environmental setback of the region is the state of health of the population. According to the data of the World Health Organization (WHO), it has been shown that oncological diseases still occupy a leading position in the general structure of morbidity and mortality among the main chronic noncontiguous diseases. Over the past decade, there are an increase generally in both neoplasm’s and the number of oncology cases - almost 1.4 times according to the statistics of the Ministry of Health of the Russian Federation [13,15]. A statistically unimpeachable increase in the number of patients suggests the solution of vital problems not only in the way of early diagnosis and treatment, but also in the study of potential factors that play an important role in the oncological diseases. The article presents the results of a statistical analysis of the prevalence of oncological diseases associated with biogeochemical factors of individual territories of the Chuvash Republic using the method of a comprehensive study of the cause-and-effect link of the “health-disease” process [18-19].
