Can cell phones cause brain cancer? It’s been the focus of discussions, arguments, studies and bloggers for decades now. So when do we really find out?
Thankfully, there’s the Interphone study, launched 10 years ago and studying 10,000 participants spread across 13 different countries. Those concerned with The Answer have been waiting for the results with increased anticipation. And, here it is, summed up by Dr. Elisabeth Cardis, leader of the Interphone study:
Until stronger conclusions can be drawn one way or another, it may be reasonable to reduce one’s exposure [to cellular radiation]. It can’t hurt. — Dr. Elisabeth Cardis
“It can’t hurt?” So, it turns out that the long awaited report, published in the Internal Journal of Epidemiology on May 17, according to Time Magazine’s May 31 issue, “is by far the most comprehensive look at the issue to date and was meant to provide a possible conclusion to the debate.” Unfortunately, the real facts of the matter: 10 years isn’t that long to study something as subtly insidious as cancer poisoning from a radiation source such as cell phones. Even so, the study does give us interesting new data to ponder, discuss and argue over while another 10 or 20 year study is pulled together:
- The study did not find any obvious connection between cell phone use and cancer, but it did find some seemingly conflicting data that muddies the discussion even further.
- Of the study’s subjects, the 10% that used their cell phones most often did exhibit a 40% higher risk of developing some form of brain cancer, as compared to those who don’t use cell phones.
- On the other hand, participants in the study that used their cell phones infrequently demonstrated a lower likelihood of developing brain cancer over people who use corded phones exclusively.
Unfortunately, even some of the data the defined the study is already out of date. 15 years ago (when the study was originally designed), using a cell phone for 30 minutes a day was considered “heavy” use. By today’s standards, 30 minutes a day might be considered moderate, particularly as people are starting to forego land-lines in favor of simply having a cell phone.
So what’s our take-away? Probably that the Interphone study is too dated and flawed. When you hear the mobile phone industry trumpeting it’s positive findings, or when you hear consumer advocates talking about it’s negative discoveries, keep in mind: They’re both quoting from the same study, a study which seems to equally support either position.
We need a new study. Unfortunately, that means we’ll be waiting another 15 or 20 years before “significant” evidence has a chance to answer this question once and for all.
