It’s official: your cell phone may cause cancer

By | June 2, 2011, 4:00am PDT

Summary: Cell phones are now up there with lead, engine exhaust, coffee, and chloroform.

I’m kind of curious about (and a little disturbed by) the recent news that the World Health Organization’s International Agency for Research on Cancer has reversed its previous position that cell phones are safe, and has added them to the list of big, bad potential cancer-causing concerns (PDF).

Cell phones are now up there with lead, engine exhaust, coffee, and chloroform. I mean, call me crazy, but I feel a lot safer placing a call on my iPhone (maybe with a nice cup of Joe in the other hand) than I would snacking on the paint chips from my grandparent’s window sills, or breathing in the black cloudy fumes billowing from a belching tailpipe.

My first reaction to the news was incredulity and slight annoyance. Remember how, in the late 70s, Sweet’N Low was demonized as cancer causing (only to be removed from the list in the U.S. around twenty years later), while in the mid-80s much scarier sweeteners like aspartame were shadily rubber-stamped by the FDA?

Doesn’t everything cause cancer? Don’t we have enough to be afraid of? What’s up with the focus on cell phones? It just doesn’t sit right with me.

A few of my thoughts and questions on the issue

As a nurse, my first question is, how real is this threat? What should I tell my clients when they ask?

Doesn’t fear of cancer cause anxiety? Anxiety is a health issue in and of itself. Cancer is a serious, heartbreaking disease. We’ve all lost loved ones to it. So we worry a lot about it, and stress worsens health.

Will saying cell phones may cause cancer have any positive impact at all on public health? Will it change people’s behavior with cell phones?

If you thought prying a cup of coffee or a cigarette out of someone’s hand is hard, just try prying away someone’s Android phone! It has been interesting, in the past four years so, watching the request to turn off cell phones in certain public situations go from being viewed as normal and understandable, to being considered a ridiculous and rude imposition.

Does anyone stand to benefit from the decision to call cell phones out as possibly carcinogenic? If so, how? Of course, there’s the non-cynical answer of an increase in public awareness of a potential hazard. On the dark side, possibilities include attention, press, political axe-grinding, and money. Who loses and who gains (besides possibly the lawyers)?

Cigarette companies knew their product caused cancer way before they admitted it. That’s known. Costly lawsuits did arise. What are the legal and financial implications of adding cell phones to the list of carcinogenic hazards? Why now? Who will be suing who? What impact will this announcement have on the tech economy?

It hasn’t really been proven that cell phones actually cause brain cancer. We would expect to see a huge upswing in brain cancer cases to match the huge upswing in cell phone use. If such a cause were completely evident, we’d be seeing some very different news stories today, stories that involve a lot less “may”, “might”, and “possibly”.

Next: What about Bluetooth (and more) »

Interesting article
ryeckley82 2nd Jun
I have been suspecting possibilities of it for a long time, with people increasingly getting cancer, and increasingly using cell phones. It doesn't take much work to put 1+1=2. I'm guilty, because I use the cell phone a bit. But I've seriously cut down over the last year or so ... I actually let it go to voicemail at certain times. People have thought I was being rude, but "me time" is a concept that everybody has lost thanks to the OBSESSION with cell phones. Not the technology itself, but the obsession to keep in touch.

One of my friends is older. He uses a cell phone only when needed as well, and prefers landline. The only time I use landline (because mine has a lot of static in it), on the other hand, is when my cell can't get a signal. But I do miss not having to worry if people can hear me clearly.
@ryeckley82 well... they also move less, drink more, eat more, take vacation less, have more stress, live longer.... now try to decide how all this correlates with cell phone use and cancer.
@pupkin_z
I agree 1+1=2 is too simplistic, there is also the question of aspartame causing brain tumors during the same time frame.
http://www.naturalnews.com/011804.html
@pupkin_z I am old enough to remember similar types of arguments for and against the smoking of cigarettes in the '40's. Producers saing no proof and a number of Doctors saying it does.
@ryeckley82 Our food and drink supply has a bigger impact on cancer than cell phones. The great thing is it cannot actually be tied to one thing or another, so companies can continue to pollute our food supply in the name of profitablity as more and more people develop various types of cancer. Our grandparents smoked and ate greasey food for decades and will likely live longer than we will.
@ryeckley82 This story is pure ********!

There is no hard substantial scientific evidence of this...any shred of such "Evidence" is inadmissible for lack of supporting evidence. Nice try trolls.
@ryeckley82
I think that 1+1=2 is Republicans+Democrats=Cancer. OMG!
@ryeckley82 There are also more computers. Do those cause cancer? There are more cars now as well. Do those cause cancer? The internet is more widespread. Does that cause cancer? Twitter is more popular. Does Twitter cause cancer? People have more pictures taken of them. Does having your picture taken cause cancer?

Correlation != Causation.
@ryeckley82
You're confusing correlation with causation. The 2 are not related. For example, there are many more soy products sold today than there were 50 years ago and more people are getting cancer now than 50 years ago, hence soy products cause cancer. 1+1=2, right? Not so much. Cell phones use RF radiation (radio waves) which are a type of non-ionizing radiation. Non-ionizing radiation is not small enough (at the wave level) to change DNA. Ionizing radiation (X-Rays) is small enough at the wave level to change DNA and does cause cancer. There is hard, concrete scientific evidence of that.
Didn't a recent report come out claiming that coffee may reduce the risk of certain types of cancer? First eggs are good for you, then they are bad for you, now they are good for you again in moderation. We should take these type of reports with a grain of salt until there is definite proof that things like cell phones are detrimental to our health.

This constant scare mongering that politicians and the media engage in should be criminal because the stress it causes is proven to be bad for our health.
@soonerproud Everything is good for you and everything is bad for you. Everything in moderation.
NEWS FLASH!

Living past 20 years old increase the risk of cancer!
@Tommy S.
lol.
I think its great when people start saying that one thing in the modern world must cause all the cancers.

Cancers may be increasing a lot, but then our life styles are so different from the past, and we a re living longer, and we are exposed to more chemicals and...

BlueTooth headset
willem@... Updated - 2nd Jun
@voska1 There is an easy solution, and it has been available for some time, BlueTooth headset, which also enables you to drive safely!
@willem@...
whats saying that bluetooth does not give you cancer!
Unlike other afflictions where there is a very direct cause-and-effect that can be found (stick a dirty needle into your arm, *POOF*, you have AIDS), it takes years of exposure to most carcinogens in order to see a result, and even then only a subsample of people exposed actually develop cancer.

Remember, cigarettes are one of the best known causes of preventable cancer, and they still only kill 1/3 of their users, and only a subset of those killed by cigarettes actually die of cancer.

Cell phones were around for quite a long time, but it's only been the last half-decade or so that they've really become ubiquitous. There just isn't going to be enough evidence to "prove" that they can cause cancer for another 20 years. This is where the "may" comes from in these studies - they're stating that there is "evidence", but not yet "proof" (a word that is actually VERY rarely used in the scientific community, as it is actually antithetical to how scientific studies work).
@daftkey

Actually, there are hundreds of millions of people who have used them for over ten years. Additionally, they tend to crank less signal power now. Juicing a massive display means you've got to make everything a lot more efficient.

That is ABSOLUTELY NOT what the WHO is saying. The WHO is not saying there is evidence suggesting that using your cell phone for 2000 minutes a month for 10 years causes brain cancer. They're saying there is a significantly significant chance that it could is a small number of people. This should be interpreted not as evidence but as an official statement that there is enough risk that we should be looking for evidence. This is a boon for researchers and reporters that possess no journalistic ethics.
How often do you even talk on the phone anymore? Most people with smartphones use the "other" features way more than actually making phone calls.

Not to mention we get more radiation from the sun than pretty much anything else.

MC_z 2nd Jun
The WHO simply said that existing studies had not definitively proved cell phones DIDN'T cause cancer. That's a long way from saying they do.

News outlets, using both of their working brain cells, then breathlessly reported what they didn't understand.
@MC_z

You're generous. I think they deliberately and unethically misled for sensationalist ratings.
This is the same kind of garbage logic that lead to PG&E getting knocked over their smart meters. These devices put out radio waves... Not radiation. They are physically incapable of causing cancer, or at least far less likely than being out in the sun.

Radio waves are radiation.
Bruizer 3rd Jun
@nickswift498

But your point is taken that radio waves are 6-7 orders of magnitude below the point needed to do molecular damage.
I haven't really heard a good explanation of how exactly cell phones are supposed to cause cancer. Microwaves don't have enough energy to blow apart your DNA.

What they CAN do is heat up your brain from the inside out. Given the brains high density I wouldn't expect that heat to amount to much, but I sometimes wondered if poor phone design or just random bad luck couldn't accidentally focus greater amounts than usual to a specific location, like an ant under a magnifying glass.

But that would still be brain damage rather than cancer and should be easy to spot.
@SlithyTove Microwaves don't cook from the inside out.
@vel0city

A lousy way of stating it admittedly, but point being that they do penetrate to some degree directly into materials.

His_Shadow 2nd Jun
The news flash is that cell phones are as likely to cause cancer as coffee and gasoline.

Everyone shut up now.
I'm just relieved that someone else mentioned the lack of quality that the cell phones have provided. Why is it that analog land lines were replaced with digital phone? digital phone conversations are one step above cell phones but still 5 below analog.

As for the main topic, it doesn't seem like we ever will be safe from harm.
@shettinger

Uh, right. You probably don't even have analog switched phone service over your landline except maybe for the last mile. It's not a question that analog sucked. The question is how much analog sucked IN YOUR AREA.
Idiocy. They don't cause cancer any more than wearing a magnetic bracelet causes good health. Cell phones do not produce ionizing radiation. The WHO should hire an engineer or two.
All too often we dismiss the possibilities just because we don't believe it's possible. Proof is absolute only to those that actually did the tests. Others go off of hear say.

There are always monetary reasons for reporting something like this. The United States is the greediest nation in the world and the best at spreading FUD to line their pockets.
I would believe that the phone manufacturers could care less if their phones caused cancer. That would kill their profits. I would believe that a competitor would spread rumors about their competition to increase their sales and market share.
I would also believe that someone would pay/bribe/coerce WHO to report something like this just to gain financially. Who, I don't know off hand but I would bet money that's probably the reason. Why else would they come out with a report that has no proof but still make you more cautious and some even get rid of their phones because it "may" cause cancer.
Being born may increase your risk of cancer. Cancer is on the rise due to baby boom. Pesticides that people spray with reckless regard are far more damaging than cell phones. Face it, our ancestors died of cancer but didn't know what it was. Back then DDT, mercury, ect wasn't linked to illness.
Think you are wrong on the coffee - I thought the latest was that some coffee drinking protected against certain cancers. Also coffee has been shown to lower blood sugar. Cell phones produce ionizing radiation so this seems less far fetched. However remember Kepler's Law - the strength of the radiation is reduced by 3x the distance - or something like that. Use your speakerphone, or Bluetooth the thing through your car stereo and you will be ok
@kvolkan

do NOT produce ionizing radiation.
@kvolkan Bluetooth emits the same type of radio waves as cell phones.
For me, the bottom line is that noone knows what we might discover next, so use some common sense together with some knowledge. For non-ionizing radio waves, the signal strength, the frequency and the amount of exposure (time) are things to keep in mind. Also, since radio wave energy strength decreases rapidly as you move away from the source (distance squared), limit your exposure. I don't spend all day in the sun without any sunblock, I don't rest my head against the microwave oven door while it is operating and I don't keep my cell phone glued to my head for long periods of time; I prefer speaker phone mode when I have a choice. Bluetooth is much lower power (and higher frequency). A wired headset may or may not help because the wire may act as an antenna to some extent.

One other thing worth knowing - modern cell phones conserve battery power by only putting out a string a signal as needed to keep a good communication link . When the reception bars go down, the cell phones radio turns up the power because the tower(s) are harder to reach than when the reception bars are at max.

Bottom line - treat with cautious respect but not fear.

2 Watts.
BobsYourUnclw 2nd Jun
That is the broadcast power of a typical phone. Assuming 100% (phone pressed to your head) of 1 side is pushed into your head and face, you get exposed to 1W of power. Depending on antenna design, maybe that 1W is concentrated on one small area.

That level of microwave radiation won't penetrate more than 1/8th of an inch into the head. I just don't see how, based on physics this can cause brain tumors. I guess the only risk might be skin cancer is shaking water molecules at such a low level could trigger an DNA corruption.

Personally, I hate headsets, I have a high quality bluetooth speakerphone on my visor and for long conversations I move to a landline anyway for comfort.

I was using peak energy as you said. The old old "bag phones" would do 3.5W. The point being that at the very worst, 1W is all you are exposed to.
Again, may and a BIG BIG MAY. Rubbish articule.

Common Sense...
matenai 2nd Jun
I am an engineer and physicist. I also have been involved with radio energy since the age of 11 and now I am 60. No signs of problems yet BUT I do my best to observe the benefits of power reduction as the inverse of the square of the distance...

Any form of radiating device is kept as far from me as possible without sacrificing the benefits of having the device. Todays cell phones and cordless land lines have great speakerphones...use them and reduce the impact by at least 100 times. Use bluetooth instead of holding a phone on your head and you reduce at least 10 times the impact. This does not mean you cannot hold a phone against your head...just reduce the cumulative effect.
