Are the studies carried out with controls...

ie - if you sat chatting away for an hour with a piece of wood held to the side of your head - would it not be the case that your head and ear would get flushed and warm due to:

1) being covered
2) being continually knocked by the object
3) being in proximity to a warm hand

Just my tuppence worth

Another thing is that just because the skin on the outside of your skull get warm/ numb (probably due to the 3 items listed above ) it doesn't mean that anything is happening inside (take that comment how you want )

Anyway... why speak on the phone for an hour? - go round and see the girl - give her a kiss for goodness sake - no more than that mind... 'till you're married!

they were serious studies and using control groups is standard practice so I don't see why not.

In the cell tissue culture experiments, they actually bombarded cell cultures in the laboratory with mobile phone radiation, not people's heads, so they had full experimental control of the environment.

You can take it for fact that Cell phone radiation heats livings cells, this is not something that there is scientific disagreement upon. What's under disagreement, is whether that kind of heating will lead to tumours or not, and if so at what levels of exposure.

Brain Tumours/Cancers are relatively rare considering the widespread use of mobile phones. However Lung cancer, Skin cancer, and Bowel cancers are very common due to exposure to Cigarette smoke, direct sunlight and certain foods all of which WE choose to expose ourselves to.

Cancer in the majority of cases is a result of lifestyle chioces, brought about by Western life expectancy in the 20th century doubling from 33 to 70 yrs.

My N80 gives me headaches if using it to call for ages,
however Wi-Fi is a bigger headache most times,

do those cause cancer?

that's the bottom line. I think that it's possible in rare cases for tumours to form in response to excesive mobile phone use, but you'd have to be pretty unlucky. Nuch better chances are you'd get something from passive smoking

However I still reckon it's prident to avoid that "numb" feeling, especially if you get headaches as well from using the phone. You may not get tumours, but there is evidence of other affects for example concentration and ability to think clearly have been shown to be affected by such brain cell heating affects, as well as general mood swings.

This could be because of long priods of concentration, Volume levels being too low or high for comfort, Perhaps too much treble in the speaker earpiece? None of these causes are carcinogenic however.

Do you mean that literally or metaphorically?

It is proven through studies that eliminate other factors (such as volume levels, phone pressure against the ear etc) that many people DO get headaches and or a numb sensation after using the phone for half an hour or more. Other factors such as dizziness, fatigue etc are also reported.

"I do not see that mobile phones used normally pose a health problem, but some people are using them for 20-30 minutes or more at time, and there is overwhelming scientific evidence that there is a hazard to health from that kind of use. "

Also, there is evidence of connection between brain tumours and mobile phone use. No hard proof, but evidence nonetheless that deserves more study:

http://www.epidem.com/pt/re/e[....]c!1390229169!181195629!8091!-1

And also there has long been strong evidence that emr affects can cause health problems and physiological effects to humans (and is proven in laboratry animals such as mice):
http://www.electrosmog.com.au/otherarticles.htm

http://www.abc.net.au/health/thepulse/s1285335.htm

Essentially, it seems that if their is a risk of tumour, it is quite low. Other health affects are more common, such as numbness and dizziness, but whether these lead to tumours is unknown.

I've read though all your links, I remain unconvinced that there are any serious ill effects.

The Saudi link was least scientific of the lot. Providing a questionaire to people on this subject simply collects data on peoples fears and apprehensions.

fair enough But I'm still not using a mobile phone for more than half an hour without a headset.

For a few weeks I had a very mild toothache, and everytime I used a phone without the headset for more than 15-20 minutes, the nerve started to really hurt, and I mean to the point I was writhing in agony. I just had to stop using the phone until I worked out it didn't happen if I used the headset. I tried this about 5-6 times before giving up trying to use it without the headset.

As soon as I stopped using the phone, or plugged the headset in, the pain went away.

That's enough evidence for me that emr affects from mobiles phones can have health affects

Those links really arn't good sources of information. Newspapers are great at sensationalist reports but very bad at reporting actual hard science. If you want to find out more about this issue then google scholar is the best tool I can advise since it will get you peer reviewed journals (or abstracts at least).

This abstract from a review of current literature sums up much of the evidence:
