The assessment of environmental health risk factors of the incidence of oncological diseases in small industrial towns

The incidence of oncological diseases in the citizens of the Chuvash Republic, Russia, remains high. The forecast for the incidence of malignant neoplasms in the citizens of the Chuvash Republic and the small towns of Alatyr and Shumerlya in 2013 to 2014 suggests a probable increase in the incidence rates. The individual carcinogenic risk from children's oral exposure to heavy metals was found to amount to 2.15E-05 and 9.52E-05 for Alatyr and Shumerlya, respectively. The children who are exposed to the highest lifetime individual risk are those residing in the town of Shumerlya – 10 new cases of malignant neoplasms for every 100,000 children of the corresponding age. In contrast, in Alatyr, there are only 2 new cases of malignant neoplasms. We have detected a relationship between environmental components and an increase in the incidence of oncological diseases in the studied areas.
