Recent research is showing that, internationally, brain cancer registries are showing a rise.
The incidence of the worst brain cancer, glioblastoma, has increased in the United States and
Denmark (Morgan et al, 2014). An Australian study has shown an overall significant increase in
primary malignant brain tumors from 2000 to 2008, particularly since 2004. Another recent study
(Zada et al, 2012) shows an increase in brain tumors in three major cancer registries in the
United States. The increase seen is in the frontal and temporal lobes, which are the two regions
closest to where a cell phone is typically held.
There is a long latency period for brain tumors – from 5 to as long as 50 years. Since cell
phones have only been widely used in the US for two decades, the full increase in cancer rates
is still unknown. Rates of autism, ADHD, diabetes, food allergies and immune diseases are
skyrocketing, and it is understood that this increase cannot be due to genetics alone as the
genome does not change in two decades. Environmental factors are increasingly thought to be
behind this sharp rise. Like air pollution and chemical exposures, electromagnetic fields have
been shown to increase stress on biological systems and impact the developing brain. Some
research is pointing to a synergistic effect between toxic exposures such as lead and
electromagnetic fields.
