Recent years have brought much public worry about the possible link between cell phones and brain tumors. And scientific studies have done little to lessen people’s fears, since the results have been frustratingly inconclusive.
Many experts have been slow to jump on the bandwagon, since plenty of other studies have shown no link, or an unconvincing one.
Just a few months ago a large-scale study reported that the risk of two types of brain tumors (glioma and acoustic neuroma) was double in cell phone users over the period of ten years — the authors even volunteered a number of tips to help users reduce their risk. The World Health Organization (WHO) then stated that cell phones are "possibly carcinogenic to humans." Still, many experts have been slow to jump on the bandwagon, since plenty of other studies have shown no link, or an unconvincing one. >
Now, another large scale study reports no increased risk in cell phone users over the 10 to 15 years that people have been using them. The authors reviewed a previously published study that quizzed 13,000 people about their cell phones use over a period of 10 years.
So, whether this new study will affect how the public, the media, and the scientific community view cell phone safety remains to be seen. The authors point out that because of the relative recency of cell phone use, it may take several more years, or decades, before we know more. We’ll be sure to stay tuned as more research in this area unfolds.
The study was carried out by researchers at the British Institute of Cancer Research, and published in the July 1, 2011 online issue of Environmental Health Perspectives.
