Study Shows Cell Phones Safe 210

PreacherTom writes "In a move worthy of the Mythbusters, scientists in Denmark tracked over 420,000 cell phone users over the course of 21 years in an attempt to determine if the urban legend that cell phone use causes cancer is true. Their results: the RF energy produced by the phones did not correlate to an increased incidence of the disease. Please note that this doesn't make chatting on the highway at 85 mph any more safe." From the article: 'This so-called Danish cohort "is probably the strongest study out there because of the outstanding registries they keep,' said Joshua Muscat of Pennsylvania State University, who also has studied cell phones and cancer. 'As the body of evidence accumulates, people can become more reassured that these devices are safe, but the final word is not there yet,' Muscat added."

    Even the summary of the article doesn't agree with the title of the article. Whilst I am of the opinion that mobile phones are safe, it is impossible to prove it. It is possible to demonstrate that it is almost certainly not the case, but it is impossible to demonstrate to a mathematical certainty that mobile phones (or any other treatment, e.g. medication, having blonde hair, being called Fred) is safe.

    Hey, at least there's a mechanism. Stress has been implicated in contributing to a lot of other diseases, why not cancer?

    They didn't take into effect the amount of vehicular accidents that are caused by inattentive cell phone drivers. This is probably the most unsafe aspect of them

    They've studied cell phones since 1985? They were only made legal in the U.S. in 1983, and used very different tech than today. I'm skeptical.

    In a move worthy of the Mythbusters, [...]

    If I had an important paper published in a respected scientific journal and someone told me my work was 'worthy of the Mythbusters' I'd punch them in the face.

    That's true with anything, including that what you see is real. I don't have the time or the energy to teach you basic philosophy but this is not a new debate. Descartes thought about it, and many have after him. For the best modern thought on how scientific method works and how we prove things empirically, get the Logic of Scientific Discovery by Karl Popper.

    If the cell phones 20 years ago didn't cause cancer, then todays less powerfull phones certianly do not.

    Or perhaps any less safe than chatting with a passenger while drinking a soda at 85 mph, unless we have data to show otherwise.

    Sweden (not Denmark, but close) did start an analog cell phone network in 1981: the NMT system. The system was standardised to be the same within the nordic countries, of which Denmark is one. (Japan started even earlier, in 1979)
    It is not always correct to assume that USA is on the edge of technology development and deployment.

    This is not at all a "move worthy of MythBusters" as the submitter stated. Mythbusters is entertaining and generally informative television, and this Danish study sounds solid, but the methodologies are totally different, for the obvious reason that sifting through hundreds of thousands of medical records accumulated over many years and applying complex statistical models to them does not make for compelling television.

    You know, I can smoke one cigarette a week for 15 years, then a pack a week for the remaining 5 years and probably not get lung cancer and the end of that 20 year time period. That doesn't exactly mean that smoking isn't harmful.
    Perfectly true, you probably won't get lung cancer. However, if instead of considering just yourself, you survey 420,000 people over that same 20 years, the incidence of lung cancer among that group will be very much higher than a control group. It's called a scientific study. In fact, TFA is about a scientific study exactly like that one! What a coincidence.

    Putting a device that emits radiation next to your head is harmful.
    And you could give me what evidence for that statement? What study are you quoting? Or did you just make it up on the spot? I'm guessing the latter.

    One study does not a conclusion make. Usually, in scientific research, you need three independent studies before most scientists will draw a conclusion.

    My question is - who paid for this study? Was it Nokia (caveat, I own shares in them) or some other cell phone firm?

    Obviously this study has a lot more scientific integrity than what the Mythbusters do, but to say that what they do isn't science just isn't true.

    Mythbusters is probbably the only show on TV that actually DOES science and shows what it is rather than just acting as a mouthpiece for science. The do everything that other scientists do, albiet within the confines of a television show. They repeat experiments, they accept "peer review", they establish controls. They do everything but publish a paper in a journal. Tell me how what the Mythbusters do isn't science?

    It might not be something you'd want to site in a research paper, so it's not really up to the standards of acadamia, but calling what they do not science is simply wrong.

    "100% conclusive"

    There is no serious study that can be 100% conclusive. If anybody comes to you preaching 100%-fool-proof numbers that is a sure tale-tale sign you are dealing with a wanker. What you can do is set extremely low chances for your study to be wrong (less than 2%, less than 1%, etc). Unfortunately the closer you get to zero, the more effort (read size of your case study) you must put into it. At some point you have to have some faith in probability.

    There will always be incredulous people or consipiracy theory types. Not much you can do, there have been now plenty of serious studies which have not found enough evidence to correlate cell phone usage to cancer, to me it is enough to feel safe while using it, but as I said no matter how many studies you make, there will always be people who chooses not to believe in them.

    You better stop your needless worrying. According to my new theory, worrying about cell phones causing cancer causes cancer. Don't believe it? Well no one has disproven it yet!

    Also according to my made-up numbers, 10 years ago people used to only worry about cell phones causing cancer 5 minutes a day. These days with people like you around people worry about cell phones causing cancer 20 minutes a day! Maybe the worrying wasn't detectable back then, but it is now! We'll only know in 30 years!

    Putting a device that emits radiation next to your head is harmful. How much? Who knows.

    Worrying about dangers that don't exist is harmful. How much? Who knows. But if I state things as if we don't know anything about it, that totally false sense of uncertainty sure sounds scary.

    My prescription includes making fun of people that don't understand science. ;)

    You have to remember that many times Jamie and Adam are looking for aggregate effects and not the minute differences that professional scientists are looking to find. A lot of professional science is attmepting to increase the resolution or accuracy of previous experiments. Hurricanes and straw, crashing cars, exploding cell phones, most of these experiments are more concerned with specificity than sensitivity, i.e. whether a particular event does or does not occur rather than to what degree.

    Just like science, the methods Jamie and Adam have used over the years have improved as have the certainty of their results.

    > One study does not a conclusion make.

    That depends on the study...most importantly, on its size. 21 years and 450,000 subjects makes for a pretty damn solid conclusion. And where are the studies that show any other conclusion?

    Could you show me the three independent studies that prove this fact?

    Actually, what has been more often proved is that it doesn't matter how many studies you do - some people are terminally clue resistant and will continue to believe whatever the hell they feel like [wikipedia.org] regardless of evidence.

    'And where are the studies that show any other conclusion?'

    This one was reported by slashdot some time ago. The Swedish Cell Phone Study [slashdot.org] said there was a 240% incerease in risk for heavy users.

    It was done over ten years, and was considered better than previous studies. I think this debate is not over yet, and we'll probably see more studies claiming cancer causing and non-cancer causing over the next ten years plus till something completely conclusive happens, or we humans start using a new form of communication which does away with mobile phones altogether, as it's easier not to lug a mobile phone around. Then the debate might start a new around the new device.

    You are a genius. You have saved countless lives. Now that we have a way to overcome the blood-brain barrier we can administer live saving drugs to the brain area. Curing many untofore incurable diseases! Why haven't we thought of this before. Pray what is the scientific peer reviewed article so I can reference it and win my Nobel prize.
