Mobiles give you brain cancer?

Perhaps I'm wrong...

Perhaps I'm wrong, but at least in the US, the max power output (legal) of cellphones is (and used to be) around 3 watts, not 6 or 7. Other than that, a good article I think, if nothing new.

WIKIPEDIA??????????

FIRE HIM!

How about testicles?

Like I imagine most guys, I carry my mobile in my pocket, dangerously close to my reproductive organs. So following the "research" that shows the deleterious effects of microwave radiations, should we expect a stiff increase in the amount of testicular cancer? Likewise, are we going to observe a sharp increase in the amount of genetic defects in the newborn, Chernobyl-like?

Good article

We need this man on Panorama. I'm glad someone has finally mentioned the TV transmitters in the frequency band just below GSM900 pumping out 20kW+ (100 - 1000x the power of a GSM cell site!!) - no mass hysteria here in case it interrupts eastenders.

Oh Noes

Each year about 20,000 people in the USA are diagnosed with brain cancer. So if your chance of getting brain cancer was doubled you would have about 0.013% chance of getting brain cancer in a year!

Of course other studies have found no link between mobile phones and brain cancer. Maybe mobile phones causes paranoia and fear of disease.

I Keep My Brain In My Trousers

To be honest I am far more worried about the effect that my phone has on my balls, most of the time it is far closer to them than my head :)

re: How about testicles?

Well according to the article, you'll just end up with hot balls, which should place the mobile in the same danger range as thongs, skinny jeans and Dell laptops.

Mobiles

If you are not sure what to believe then the answer is to see what the insurance companies are doing. If they are doing nothing then no worries. If on the other hand they are treating this as the next asbestos then you should probably consider changing your behaviour.

"Radiation"

It smacks to me like the old "power lines cause leukemia" theory. There was some spurious link to substations/power lines and leukemia because of the magnetic field. Of course, the researchers forgot to work the other way and look at what happens to powerplant workers near much bigger magnetic fields all day. Same with this, pick on the phone ignore all the other radiation out there. Heck, you get EM emissions every time you flip the light switch.

Also - have a google search for magnetic bracelets to help with arthritis.

And Nicolas, don't worry about your genitals - phones only really transmit a lot when making a call, so unless you use a hands free kit from your pocket you should be fine. (Not that I admit for one second that cellphones are dangerous)

Heres another source for you, how about CB radios and all similar devices? I know a CB can legally put out 4W. I also used to know people who mod them to more than that....

Correlation != Causation

Even if further study doesn't invalidate the statistical link, we still lack a plausible mechanism by which non-ionising radiation could damage DNA, thus giving rise to cancer. For this type of damage to occur you need ionising radiation or a chemical carcinogen, such as smoke or tar - which is why the initial statistical link between smoking and lung cancer sent out strong warning signals about the dangers of smoking.

A further point - these types of cancer are rare. Doubling a 1 in 100,000 risk is still a very unlikely 1 in 50,000 risk, even though it *sounds* quite scary.

I don't think I'll be investing in a tin foil hat just yet.

Cause/effect

We can't expect people to try and understand simple concepts like cause and effect, let alone the difference between correlation and causation. I went to a good school and the philosophy of science wasn't taught until post O-levels. Psotulate, theorem, hypothesis/null hypothesis. Not easy to teach in the face of the non-rational world view peddled by the mass media: spend money on the lottery; it will make you happy!

Meh.

Cooked nuts anyone ?

Quote "To be honest I am far more worried about the effect that my phone has on my balls, most of the time it is far closer to them than my head :)"

I can second this, I used to carry my old, analogue mobile phone in my right pocket all the time, with headset plugged in (an old Nokia 101). I developed a (fortunately) non-cancerous tumour at precisely the point where the antenna stuck out of the phone.

Since then I am MUCH more careful about where I keep my phones, I, for one, don't fancy the thought of nuke bollocks.

Dear oxo

"20kW is the heat lost in the amplifier, not radiated."

Yep. That's why the bit you were quoting says " can also be viewed as a 20 kilowatt electric heater". They're talking about where the other 2% goes. They aren't /denying/ that it can also be viewed as a 980 kilowatt *transmitter*.

Scientific integrity.

"There's one final area worth focusing on: The effects of wireless transmissions on naked flesh vary according to spectrum."

So why use TV and other microwave transmissions as evidence that these emissions are harmless? They're on different wavelengths!

If you're going to knock others for being unscientific, you must be scrupulously scientific yourself. Leave holes and they'll only be picked at!

Thankyou for Smoking

Anyone else seen this excellent movie? Right at the end when he leaves the tobacco lobby and joins up with the mobile phone industry.

He asks the CEOs if cell phone use leads to cancer, and after a few mumbles and excuses..

"Repeat after me.. Although there is no current evidence that links cell phone use to cancer, we are continuing to study this issue.."

Remember those words, just about everyone from the department of agriculture in the US to the nuclear fuel treatment plants in the UK have said something similar. It doesn't actually say everything is fine, it just appears to. It doesn't say they'll tell anyone if they find out something bad, it just appears to. It doesn't even say they've hired real scientists to do the research, it just appears to.

Powerlines and Schools underneath - epidimiology and toxins?

Regarding the oft-raised stories of increased cancer rates from kids on schools built underneath Powerlines in the USA, the thought just occurred to me - I wonder if anyone did a deep analysis of what chemicals they may use when clearing the land for the powerline run?

I can even, donning conspiracy-theorist cap here, see a savvy lawyer for the power companies seeding the rumours about the powerlines themselves being the cause, knowing it's refutable, so as to divert attention (literally) away from the ground!

BIRTH DEFECTS & PREMATURE BIRTH

Premature birth is the #1 cause of newborn death. It has reached epidemic proportions in the U.S., endangering the lives of more than half a million babies. And it's growing at an alarming rate.

http://walkamerica.org/

The UK's Stewart Report, Rats and Mice subjected to an increased exposure to EMF radiation (like a mobile phone / mast). suffered symptoms like a significant increase pre-mature birth, still birth and birth deformaties.

Section 5: Scientific Evidence.. Look for tables with test results done on animals;

http://www.iegmp.org.uk/report/text.htm

Children with Birth defects in the UK is sky-rocketing.. nobody knows why....

Research has found that one in every sixteen babies born in rural mid Devon in 2002 had at least one defect recorded by the Office of National Statistics [ONS], compared with less than 1 in 630 babies born in London’s Islington during the same year.

Mobile Phones, Mobile Masts or Genetically Modified Food???

One myth needs correcting

I go along with the sentiments of the majority of contributors but there is is one persistent myth in Guy's commentary:

Water molecules do not resonate at 2450 MHz and microwave ovens need not operate at that specific frequency. In fact, ANY radio frequency from 3 kHz to 300 GHz will heat in a similar fashion if enough power is applied. Indeed folk or a certain vintage will remember a medical deep tissue heating treatment called diathermy which operated at 27 MHz (CB territory!). This is why TV transmitters (470 - 860 MHz) operate on low power when some poor souls have to climb the mast to paint it or replace the bulbs in aircraft waring lights.

Microwave ovens for domestic use operate at 2.45 GHz because

a) A licence free slot is available there worldwide for ISM (Industrial, Scientific, Medical) use.

b) The RF circuitry eg the magnetron frequency generator are relatively cheap and easy to mass produce at that frequency.

c) The internal dimensions of the cavity in which the heating takes place and the waveguide feed are convenient for domestic equipment.

Some professional ovens however work at 915 MHz (GSM mobile phone territory!) where the functioning parts are pro-rata larger.

The basic mechanism of the heating is the same as for conventional infrared ie vibration due to absorbed energy except that in the case of microwave ovens this is accomplished due to the propensity of bipolar water atoms and some fat molecules to twist in the applied electromagnetic field leading to friction.

Who's ill-educated?

I've got a Ph.D. in physics from Berkeley, and years of publications.

Back in the 60's Allan Frey explained that frequencies in the 500 MHz-5 GHz

range penetrate skin and skull much better than your car headlight ever will.

The big about fat molecules above is probably a bit off. It's the water molecules

that are in contact with fat that will heat the quickest. They don't have hydrogen bonds holding them in place. So the water right at the cell membranes reaches near boiling temperature. This of course causes a heat shock response, which has been documented in recent published papers (ERK1/2 response). What happens next?

Note that the rate of Alzheimer's started climbing by a factor of 10 a few years (1978-1983) after the first million microwave ovens were sold (1975). It then leveled off (thank god). But, starting in 2000 (five years after the first sale of 1 million cell phones) is going up again. It's going up significantly after correction for growth of the older segment of the population.

And, by 2050, Alzheimer's is projected to bankrupt the USA.

I like the comment about PR firm employees. Read the book "Toxic Sludge is Good For You" for more on that.

UV and Microwave Radiation

Actually, UV radiation inflicts its damage by the creation of the highly reactive singlet oxygen (O), a reactive oxygen species (ROS) (though not technically a free radical), via the breakage of the bonds of diatomic oxygen (O2) found in the skin. The singlet oxygen ROS will then wreck havoc by damaging DNA, mitochondria, and the cell wall, and can very well bring about the death of a cell. The damage caused by a single hit of the singlet oxygen ROS is autocatalytic in nature in that it will set off a chain reaction where more and more (hundreds of) free radicals are created, which hence cause more damage.

It is said that 80% of vitamin C stores in the skin are depleted after just half an hour in the sun. Since vitamin C is also an antioxidant preventing free radical damage, its depletion can very well lead to skin cancer.

Interestingly, there is ample evidence to suggest that the now ubiquitous exposure to UV's cousin, microwave radiation, causes the same kind of reactions in the body - since microwaves are in fact used specifically to create singlet oxygen in technical applications - and perhaps on a much deeper level since we know that microwaves can penetrate the body deeper than UV.

Research has actually shown very clearly that exposure to microwave radiation caused the formation of free radicals while also depleting the body of its vitamin C stores, on top of depleting the body of a number of its natural antioxidants like superoxide dismutase (SOD), glutathione, CoQ10, and melatonin.

Actually, one of the major mechanism's by which nuclear radiation causes damage is by the creation of a flood of what is called they hydroxyl (OH) ROS when water in the body undergoes ionization after being subjected to ionizing radiation.

So, what can one do to protect oneself? Well, eating lots of tomatoes, which contain lycopene, one of the most powerful singlet oxygen quenchers is one important strategy. And since we also know that vitamin C is depleted, taking it in large doses is should help to replenish what is being lost just by living in this world.

Taking lots of other kinds of antioxidants would also probably be a very good idea since there are a number of different kinds of free radicals/ ROS (Superoxide O2-, Hydrogen Peroxide H2O2, Lipd Peroxyl LOO, Nitric Oxide NO, Alkoxyl RO, Peroxyl ROO, and Peroxynitrite ONOO) formed in the body and specific antioxidants are known to be good at mopping up these specific free radicals.

Some antioxidants shown to have protective abilities are grape seed extract, gingko biloba, vitamin E, milk thistle, bilberry, blueberry, leutein, zeaxanthin, carotene, astaxanthin, CoQ10, and ALA to name a few.

Since microwave radiation has also been shown to lower counts of a white blood cell called natural killer (NK) cells - which are the body's first line of defense against pathogens and known to attack and destroy both cancer and virally-infected cells - it might also be a good idea for those concerned about their health to take a natural product called Transfer Factors, shown to considerably boost NK cell counts.
