Does Cell Phone Radiation Cause Cancer?

August 28, 2019

[Music] when it comes to the potential human health effects of cell phone use sir if you text excessively you might end up with a crick in your neck or even a broken neck for you or someone you hit if you do it while driving on the other hand think of that countless lives that have been saved on the road because people are now able to so quickly phone in emergencies but what about cancer since the turn of the century there have been studies suggesting up to a doubling of brain tumor risk with long term cell phone use on the side of your head and where you use it to talk that’s important since the radiation only really penetrates a few inches into your head looking from the back of someone’s head or from the top you can see why you might develop cancer on the one side of your head over the other since it’s such a local effect you can see why there are recommendations for like using the speaker function or using a hands-free headset which can reduce brain exposure by a factor of a hundred or more and this includes Bluetooth headsets this may be particularly important in children who have thinner skulls yeah but cell phone radiation isn’t like nuclear radiation it doesn’t damage DNA directly like gamma rays from an atomic bomb or something but it does appear to be able to damage DNA indirectly by generating three radicals out of a hundred studies that have looked at that 93 confirmed these oxidative effects of the kind of low intensity radiofrequency radiation that comes out of cellphones okay but does that oxidative stress translate out into DNA damage most studies found it did finding signs of genotoxicity damage to our genes our DNA or chromosomes give it a lot of those studies were in a petri dish or lab animals I’m less interested in whether Mickey or Minnie are at risk what about brained tumors in people yes some population studies found increased cancer risk other studies did not hmm I wonder if the source of funding of those studies had anything to do with it some of the studies were funded by cell phone companies researchers suspected that studies would be less likely to show an effect if they were funded by the telecommunications industry which has the obvious vested interest in portraying the use of cellphones as safe so they ran the numbers and surprise surprise found that the studies funded exclusively by the industry or indeed substantially less likely to report significant effects most of the independently funded studies showed an effect most of the industry funded studies did not in fact had about ten times fewer odds of finding an adverse effect from cellphone use that’s even worse than the drug industry study sponsored by Big Pharma about their own products only had about four times the odds of favoring the drug compared to independent researchers though Big Tobacco still reigns supreme when it comes to big bias why do research articles on the health effects of second-hand smoke reach different conclusions well turns out studies funded by the tobacco industry had a whopping 88 times the odds of concluding it was not harmful so 10 or so times for telecom puts it more towards the drug industry end of the bias spectrum there’s conflicts of interest on both sides of the debate though if not financial then at least intellectual where it’s human nature to be biased towards evidence that supports your personal position and so you’ll see flimsy signs like this published where there appears to be a disturbingly straight line between the states with the most brain tumors in those states with most cellphone subscriptions but come on one can think of lots of reasons why states like New York and Texas might have more brain tumors and cell phones than the Dakotas that have nothing to do with cell phone radiation sometimes you might even see outright fraud with allegations that academic research is that authored two of those genotoxicity papers and this very review were involved in scientific misconduct which they didn’t pointing out that their lead accuser turned out to be a lawyer working for the telecom industry and on and on whenever there’s a trillion dollar industry involved whether it’s the food industry or the tobacco industry the drug industry or the telecom industry there’s so much money involved that the science can get manipulated take the nuclear energy industry decades of high-level institutional cover-ups as to the health consequences of Chernobyl for example with the official estimates of resulting health problems a hundred or even a thousand times lower than estimates from independent researchers was it just four thousand who would eventually die from it or nearly a million people it depends on who you ask and who happens to be funding whoever you’re asking that’s why when it comes to cancer all eyes turn to the IAR see the official World Health Organization body that independently and objectively tries to determine what is and is not carcinogenic we’ll find out what they concluded about cellphones next [Music] you

    I studied wireless technology and whenever we used APs (access points) which are basically antennas for spreading signals in buildings, the first thing we had to do in the labs was to turn the signal power to 1. Our teacher pointed out that the first nations to implement wifi such as France had elevated risks of central nervous system cancers and tumors. If you're a truck driver, spend a lot of times on highways or god forbid live next to a highway, you have much more elevated risks of cancer since the Antenna's power is much higher next to highways. Not all countries have the same regulations on the maximum antenna power you're allowed to set in cities as well.

    Speaking of science manipulation, it would be really interesting to see a video about vaccines given the alleged hiding and alteration of data by the CDC that was exposed by some internal whistleblowers. I also hear that a former CDC head is now president of Merck. Is this supposed fraud a serious possibility and vaccines something we should be wary of? I ask also because in Italy the health minister has now made 10 vaccines mandatory for children, and it's something the population is really concerned about.

    Unsurprising that the vast majority of your demographic saw this video as justification for their long-standing opinions. You've managed to cultivate a strange following that watches exclusively peer reviewed, empirical content, yet ultimately doesn't care about anything other than confirming what they already know (and conforms to a trend, exacerbated by these videos, of some sort of stereotypical vegan and pseudoscience anti-technology hippie). Showcased wonderfully by the dismal comments on this video. Do they not annoy you, someone to who data is the ultimate arbiter? Or are they part and parcel of running a YouTube channel? Or maybe, more cynically, encouraging these sorts of views is the entire point.

    There are no objective organizations when money is involved. Science is not about the answer, its about the question, thus as long as the big money companies are funding PhDs, which they are, the questions will reflect a desired answer. I dont care if its the NIH or the WHO, science is deeply rooted in who's footing the bill, and what consequences there will be if we ask the right questions.

    If there is a positive association then what is the risk level? Well, next video. I wonder if it turns out to be something like the issue of living close to big power lines. The only risk seems to be very weak association with childhood leukemia and big power lines; IIRC, it less than doubles that risk from something like from one to almost two out of a hundred. If it is that small then there is practically nothing to do about it.

  • Reply Travis Godfrey Evans October 5, 2017 at 3:22 am

    Eh.. Okay there's issues with all the conspiracy cognitive-dissonance idiots in the comments…

    Firstly, you'd have to be on the phone a HUGE amount, which nowadays we are with texting being more popular.

    Second, most people use earphones and their earphone speakers to chat, and their phone is in their pocket. That will reduce the risk greatly.

    Third, you're watching these videos, so I presume you eat a healthy diet, the free-radicals can be dodged pretty easily if you're healthy.

    Fourth, technology is getting better and better and slowly phones are releasing less of this energy, so you have little to fear.

    Finally, this video too misleading, I love you Greger, and I approached this with an open mind, but you can't go ignoring studies. Many show no correlation, and no increase in tumors and various types of cancers. I chose to go vegan despite being raised in a omnivorous society because that's what studies and facts showed me, the same as I believe in science, and don't believe in the chakra's, the third eye, or the illuminati. And while I am not saying this is as unrealistic as that, I am saying there is little to no evidence supporting claims like this, it's a waiting game, and to be fair, you should hold back more, because you release a lot of videos showing some amazing studies, but you need to refrain and wait. Be patient.

    Check out a video by Veritasium 2 years ago.

    Since the invention of cell phones the amount of brain tumors hasn't gone up. This is pretty conclusive evidence that it probably doesn't cause cancer, unless the tumors will take decades to form (longer than we've been able to observe) and then we're all screwed.

    In 2011 The World Health Organization classified EMF (electromagnetic radiation from things like cell phones, wifi, baby monitors, cell phone towers etc.) as a class 2B human carcinogen (possible human carcinogen). Since then, scientists from around the world have petitioned the WHO to reclassify EMF as a class 2A human carcinogen (probable human carcinogen). Though, aside from cancer risk, this radiation has been shown to affect human physiology in a myriad of other ways.

    Great video, however, the focus only on cell phone use and cancer is a bit myopic and almost a red herring. To truly understand the threat of man-made non-ionizing radiation (EMF/EMR), one must consider all frequencies including power lines (50/60hz) and dirty electricity as well as the dozens of linked symptoms and chronic ailments that can be caused by these relatively novel exposures.

    For example, a person can have never owned/used a cell phone but still have abnormally high exposures to wireless and wired electromagnetic fields in their home and work environment, which will increase their likelihood of being sicker, sooner. Smoking cigarettes clearly increase your chance of getting cancer, but let's not forget about 2nd/3rd hand exposures to tobacco and the many other health problems to which they contribute.

    Cell phones are a small piece of the EMF puzzle. Proximity to power lines/substations, house wiring in the bedroom, DECT cordless phones, Wifi routers, cell towers, "smart" everything are cumulatively much more important than the question of whether cell phones cause cancer.

Forget your phone or even the RADIO or TV, why is there static between stations? It's the universe's cosmic microwave background radiation smashing you 24/7. Same shit.
