Cell Phones and Brain Cancer: A Mother Jones Symposium


From Mother Jones this morning:

It’s the moment we’ve all been dreading. Initial findings from a massive federal study, released on Thursday, suggest that radio-frequency (RF) radiation, the type emitted by cellphones, can cause cancer.

I guess it’s up to me to present the authorized opposing viewpoint. I’m going to outsource it to Aaron Carroll, who’s pretty annoyed:

 It was a rat study….9 hours a day, seven days a week….At the end of the study, survival was lower in the control group of males than in all the exposed males. Survival was lower in the control group of females for two of the three exposed groups. Yet no headlines blared that cell phones extend life.

….Now let’s get to brain cancer….no significant differences in the incidences of lesions in exposed male rats compared to controls….No differences were seen in the female rats at all. The cardiac schwannomas were more compelling, but again, only for males. No differences for females.

….I didn’t see any sample size calculation….power calculation….about 14%. This means that false positives are very likely. The cancer difference was only seen in females, not males. The incidence of brain cancer in the exposed groups was well within the historical range. There’s no clear dose response….Also, this: Cell phones are UBIQUITOUS in the United States. If they were causing cancer, we would expect to see rates of cancer going up, right? That’s not what we’re seeing. They’ve been decreasing since the late 1980’s.

I’d add one more thing. This is going to sound snarky, but honest, it’s not. Here it is: people don’t use their cell phones much to make phone calls. This is especially true of young people, which means it’s a trend that will only get more pronounced with time. But there’s really no way that a cell phone used for, say, texting or Snapchatting could cause brain cancer. Maybe skin cancer? Fingertip cancer?

On the other hand, maybe it’s not the cell phones at all. Maybe it’s the cell towers. Has everyone here read Waldo? Maybe you should.

DOES IT FEEL LIKE POLITICS IS AT A BREAKING POINT?

It sure feels that way to me, and here at Mother Jones, we’ve been thinking a lot about what journalism needs to do differently, and how we can have the biggest impact.

We kept coming back to one word: corruption. Democracy and the rule of law being undermined by those with wealth and power for their own gain. So we're launching an ambitious Mother Jones Corruption Project to do deep, time-intensive reporting on systemic corruption, and asking the MoJo community to help crowdfund it.

We aim to hire, build a team, and give them the time and space needed to understand how we got here and how we might get out. We want to dig into the forces and decisions that have allowed massive conflicts of interest, influence peddling, and win-at-all-costs politics to flourish.

It's unlike anything we've done, and we have seed funding to get started, but we're looking to raise $500,000 from readers by July when we'll be making key budgeting decisions—and the more resources we have by then, the deeper we can dig. If our plan sounds good to you, please help kickstart it with a tax-deductible donation today.

Thanks for reading—whether or not you can pitch in today, or ever, I'm glad you're with us.
