Geospatial analysis of the incidence of lung cancer in the population of the Republic of Tatarstan and its relationship with natural and anthropogenic factors

Introduction. The article presents the results of an assessment using geographic information systems of the spatial characteristics of lung cancer incidence in the population of the Republic of Tatarstan and its dependence on air pollution with carcinogens and solar activity. The objective of the study was to identify patterns of lung cancer incidence in the population of the Republic of Tatarstan and its dependence on air pollution and the cyclicity of solar activity. Results. The study demonstrated a high degree of correlation between the comprehensive index of air pollution with carcinogens IZAk and the incidence of lung cancer in the population (r=0.79 at the level of α=0.05). To identify the relationship between solar activity and the incidence of lung cancer, a statistical analysis of the long-term incidence rate of the population and the level of solar activity was carried out using the relative number of sunspots (Wolf number - W). The correlation coefficient between W and the incidence of lung cancer is significant at the level of α=0.05 and is r=0.72, which indicates a noticeable strength of the relationship between the studied indicators. Conclusion. Improving the monitoring system, monitoring the state of the external environment, and measures to prevent air pollution will help reduce the incidence of cancer, including lung cancer.
