Joel M. Moskowitz, Ph.D. has created a Fact Sheet on the recent NTP study that summarizes some “Spin” that is being presented in the media on this important study and its findings. These biased statements are being used to sow seeds of doubt in relation to data quality and the implications this research brings to the table. A separate column presents the “Facts” that has in some cases been sourced from decades of peer reviewed research.
Dr Moskowitz is a Director, Center for Family & Community Health, School of Public Health at the University of California, Berkeley.

The graphs below helps tell the story from the perspective of real Human brain tumor incidence data. The first graph is based on brain tumor data from The Netherlands.
“The black segment of each column tracks the incidence of glioblastoma multiforme (GBM), the most aggressive and deadly type of brain tumors. While the total incidence of all types of brain tumors in The Netherlands rose at the rate of only about 0.7% per year, the increase in GBM was about 3.1% per year —that is, the incidence more than doubled over the period 1989-2010. (Follow the thin red line we superimposed on the histogram to track the trend.) This is a statistically significant increase. At the same time, the rate of all the other types of brain tumors went down; these changes are also significant. The higher incidence of GBMs is being masked by the lower rates of the other types of brain cancer.
