US cancer fatalities are in decline

“According to the American Cancer Society, “the largest single-year drop ever recorded” for cancer deaths in America took place from 2016-17 in the amount of a 2.2 percentage point decrease. This is the most recent time period that data is available.” click here

Heavy Metals in Drinking Water and Cancer Incidence in Black Sea Area of Turkey

Colak EH, Yomralioglu T, Nisanci R, Yildirim V, Duran C. Geostatistical analysis of the relationship between heavy metals in drinking water and cancer incidence in residential areas in the Black Sea region of Turkey. J Environ Health. 2015 Jan-Feb;77(6):86-93.

In the study described in this article, the authors examined the relationship between heavy metals in the drinking water and cancer densities in residential areas. The Turkish cities of Trabzon, Rize, and Giresun in the eastern Black Sea region were chosen as the study areas. Cancer registry data, population information, heavy metal chemical analysis results for drinking water, and other spatial information for the region were collected in a database designed in GIS. Information on a total of 13,012 registered cancer cases from the years 2000-2007 was obtained from a cancer record center and depicted spatially on a map. The incidence values explaining cancer density in residential units were calculated. Chemical analyses were then conducted to determine the presence of 17 different heavy metals by collecting a total of 541 drinking water samples. It was determined that among the 17 analyzed heavy metals, beryllium, nickel, antimony, and molybdenum had a significant relationship with cancer incidence values in the residential units.
