Brain tumors are on the rise
UC Berkeley's Joel Moskowtiz recently wrote about the increase in brain tumors in the US.
"Three independent, case-control studies have found that long-term use of cell phones increases risk for glioma (" target="_blank";Interphone Study Group, 2010;" target="_blank";Hardell et al, 2013;" target="_blank";Coureau et al, 2014). The only research to examine cordless phone use also found increased glioma risk with long-term use (" target="_blank";Hardell et al, 2013). These studies include data from 13 nations: Australia, Canada, Denmark, Finland, France, Germany, Israel, Italy, Japan, New Zealand, Norway, Sweden and the UK. After ten years of wireless phone use (i.e., cell phone plus cordless phone use), the risk of glioma doubles and after 25 years, the risk triples (" target="_blank";Hardell et al, 2013)."
The U.S. does not conduct research on wireless phone use and tumor risk in humans, did not participated in the 13-country Interphone Study, and does not participate in any of the international studies. Yet as Dr. Moskowtiz writes, there is no reason to believe that Americans are immune to these potential effects of wireless phone use. Studies bear this out.
In the US the incidence of&nbsp;glioma, the most common malignant brain tumor, has also been increasing in recent years, though some differences are noted by age group<strong;. </strong;The National Cancer Institute reported that glioma incidence in the frontal lobe increased among young adults 20-29 years of age (" target="_blank";Inskip et al., 2010). Moskowitz writes: "The incidence of glioblastoma multiforme (GBM), a highly cancerous glioma,&nbsp;increased&nbsp;in the frontal and temporal lobes, and in the cerebellum among&nbsp;adults of all ages in the U.S.&nbsp;(" target="_blank";Zada et al., 2012)."
