Investigations: Cellphone Study's Little-Noticed Appendices Reveal Cancer Links
Are cellphones safe or not? A major study of 13,000 people was widely interpreted as being "inconclusive" on links between cellphone use and cancer. However, this analysis by Trent University professor Magda Havas, who specializes in electromagnetic pollution, says the study actually did find some disturbing connections with cancer, which went largely unreported in the media coverage.
She cites the study's two little-noticed appendices that reveal an 84-percent increased risk of meningiomas for those who used digital phones for 1,640 hours or more and a 343-percent increased risk for those used both digital and analogue cellphones or if the type of phone used was unknown. As well, the study found those who used a cellphone for two to four years had a 68-percent increased risk of developing gliomas versus those who had used a cellphone for under two years. As well, there was an 118-percent increased risk for those who used a cellphone for 10 or more years.
These findings occurred, Havas writes, despite the fact that the study's methodology was biased to minimize any adverse effects from cell use. See here for the full Interphone study. (Click Supplementary Data for the two appendices that Havas cites.) The study was produced by the World Health Organization's International Agency for Research on Cancer with funds from cellphone makers.
