Comparative hygienic assessment of the carcinogenic risk to the health of the population living in areas with different levels of the incidence of breast cancer
The purpose of the research was to conduct a comparative hygienic assessment of the level of carcinogenic risk to the health of the population living in areas with different levels of the incidence of breast cancer. The paper analyzes long-term data on the structure of morbidity, the long-term dynamics of cancer incidence, the concentration of carcinogenic substances in the atmospheric air and drinking water according to the regional information fund of social and hygienic monitoring, the territorial body of the Federal State Statistics Service. Areas of observation have been established, with the highest incidence rate of malignant tumors of the mammary gland, as well as the territory of comparison, where the incidence rate is 1.7 times lower. The calculated concentrations of substances in the air and drinking water meet hygienic requirements. The assessment of carcinogenic risk showed that in the observation area, the total carcinogenic risk is at an unacceptable level both from substances contained in drinking water and substances contained in the atmospheric air, while the total carcinogenic risk in the observation area is 10 times higher. Correlation analysis established a significant correlation of weak force with carcinogenic substances contained in drinking water and atmospheric air: chromium, arsenic, cadmium, which can act as an indicative indicator for establishing a causal relationship with the incidence of breast cancer. The study confirms the need to develop a plan of preventive measures to reduce the incidence of breast cancer, taking into account the existing carcinogenic load from environmental factors.
