Mobile phones 'cancer link': Mouth tumours 50% more likely after heavy use
By DAVID DERBYSHIRE, Last updated at 19:17pm on 14th December 2007

Mobile phone use raises the risk of mouth cancer, researchers claim. Five years of frequent use increased the chances of developing a tumour by around 50 per cent compared with people who had never used one, scientists found. The result raise concerns that mobiles could be interfering with the body in ways that scientists simply do not understand. Previous studies into the links between phones and cancer have generated conflicting results.

The vast majority have found no evidence of serious health risks. However, a small number have found links with cancers of the head and ear. The latest research, carried out in Israel, was published in the respected American Journal of Epidemiology. The lifestyles of 402 people with benign mouth tumours and 56 with malignant ones were compared to a control group of 1,266 people. Those who used mobiles the most were more likely than normal to develop parotid gland tumours. The parotid is the largest of the salivary glands and sits at the back of the mouth not far from the ear. Long term users of mobiles tended to develop tumours on the same side of the head as the phone was normally held. People who used mobile phones in rural areas, where the phone has to work harder to make contact with the nearest base station, were found to be at greater risk.

The cause of the heightened risk was not established. Most studies have looked at the way the electromagnetic fields created by phones warm tissue. However, the levels of the fields are thought too small to have a heating effect. Instead, some researchers believe the fields have the power to disrupt chemical bonds within cells or damage DNA.

Lead researcher Dr Siegal Sadetzki, from the Chaim Sheba Medical Centre in Tel Hashomer, Israel, was cautious about coming to any conclusions. "Until more evidence becomes available we believe that the precautionary approach currently adopted by most scientific committees and applied by many governments should continue," he said. A similar study published a year ago in the same journal based on mouth cancer sufferers in Denmark and Sweden found no increased risk. But campaigners against mobile use leapt on the findings. "This is more evidence - and strong evidence too - that mobile phones have a biological effect," said Graham Philips of Powerwatch. "It brings into question once again the official guidelines on safe exposure which are based on the heating effects - not the non-thermal effects that they seem to have shown here." However, other scientists urged caution.

The cancers studied are extremely rare. Only 400 parotid tumour cases are diagnosed each year in the UK. Of these, only 60 are usually malignant. The advice from the Department of Health is that there is still no evidence that mobiles pose a health risk. However, a Government funded six-year study in September found a "hint" of a higher cancer risk and concluded that a danger cannot be ruled out.

Presentation on Cell Phones and Brain Tumours

Wireless Phones and Brain Tumours presentation by Lloyd Morgan enclosed.

Also see answers to questions I recently raised with Lloyd Morgan, Lloyds replies are written in blue.

Dear Eileen,

I would like to answer some of your questions. First, let me direct you to the website of the Central Brain Tumor Registry of the United States (CBTRUS) where you will find in-depth information concerning brain tumors here in the US. The website is http://cbtrus.org I would encourage you to download the CBTRUS 2005-2006 Statistical Report."

Please see my answers to your questions within your text below.

Regards,

Lloyd Morgan

1) Is there a pack of information available?

The pack of information can be found at the CBTRUS website.

2) I would like to know if we are seeing a rise in brain tumours and if so what percentage and is it having an effect on children yet?

Here are a few excerpts from the CBTRUS statistical report regarding incidence increases in the Average Annual Percentage Change (AAPC) of childhood brain tumors:
pilocytic astrocytomas, the most brain tumor in children, AAPC=13.8%;
ependyomomas, another common childhood brain tumor, AAPC=6.9%

3) What sort of brain tumours are we seeing?

See the CBTRUS data

4) How long does it take for a brain tumour to develop?

Using data from A-Bomb survivors and various therapeutic X-ray treatments to the head (now banned), the time from exposure to diagnosis (latency time) is several decades. Childhood brain tumors are the obvious exception and I see children as the classic canary in the coal mine. That is, childhood tumors are a warning of impeding problems for the society as a whole.

5) What advice would he give to mobile phone users?

1) Use a headset with a cellphone. Keep them off, except when you wish to make a call or to find out who has called (a pager can be used for those that feel they must be reachable at all times).

2) Parents should deny use of cellphones to all children less than 18 years of age.

6) What area of brain tumour research should we concentrate on?

Personally, I believe epidemiology (research on the cause) is the most cost effective research (compared to treatment and/or cure) because with epidemiology we can learn the cause and likely will know how to prevent brain tumors from ever happening.

Best wishes

Eileen

RE: Interphone study question

Dear Iris Atzmon,

Thank you for your deep interest in the Interphone results.

There is no biological mechanism that could be used as the basis for an a priori cut point, thus, in Interphone, we use a variety of approaches to compare groups of different use patterns.

As you can see in the papers, other exposure definitions than the concept of a regular user depend on years of use, amount of use and a mixture of both characteristics and include subjects that use a cellular telephone daily for many years of use. This approach is being criticized for increasing the odds of chance findings, but to my mind it is justified, as it is a relatively new research area and we don't want to miss something.

Some of the analyses, especially those in which tumor location are taken into account, are based only on regular versus non-regular users, but this is due the fact that the national components have small sample sizes. Such analyses will certainly be part of the international pooled analyses.

This is why we (in our paper) and also others of the Interphone group have expressed the caveat that results should not be overinterpreted with regard to heavy long-term users but the international results should be awaited.

Kind regards

Joachim Schüz

A Microwave Expert Warns Against Masts Safety

Expert warns Irish mobile phone masts unsafe By Dan Buckley and Tom Prendeville ONE of the world's leading experts in mobile phone technology has warned that the radiation output from Irish phone masts is at least 100 times too high for safety.

His warning comes as new research reveals that long-term use of mobile phones poses an increased risk of brain cancer. According to Dr David Aldridge, a scientist who has worked developing microwave technology for the US Government, the international 'safety' limits which Ireland adheres to are out of date and totally flawed.

"What is happening is that the external signals (from mobile phones) are swamping the body's natural internal signals," he said. This can lead to cancers and a whole range of other serious medical disorders, particularly among children, he said. "Expose a cell to microwaves from a mast or phone and it interferes with the cell repair process. In the case of young children, the rate of cells dividing in half to form new ones is so fast that you end up with a vast number of what we call mis-repairs."

According to Dr Aldridge, the current international safety standards are over 50 years old and obsolete. Meanwhile, a new study into the risks associated with using mobile phones has found an increased risk of brain tumours in people who have used them for 10 years or more.

The study, by German researchers, found an increased risk of glioma, an often deadly brain cancer, in people who had used mobile phones for over a decade. However, a similar study in Britain appears to contradict these findings and concludes that there is no proof that long-term mobile phone use can cause glioma. Both studies are part of the 13-nation Interphone Study, an effort sanctioned by the World Health Organisation (WHO) to assess possible health risks from the radiation emitted by mobile phones.

The German study, conducted by Joachim Schuz and colleagues at the University of Mainz, compared a group of 749 brain tumour patients with 1,494 similar people who had not used mobile phones and found a doubling of the risk of glioma after 10 years of use. They said the number of people in the study who had used the phones for 10 years was small and the findings need to be confirmed by other studies. This same 10-year threshold has previously been reported for acoustic neuroma, a benign tumour of the acoustic nerve, by two Swedish teams.

"This result is very difficult to interpret," said Dr Schuz. "I can only say that it's still an open question whether there is a tumour risk for more than 10 years of use." The British researchers found no overall increased risk in people who used mobile phones. Although it revealed a significantly increased risk for tumours that developed on the same side of the head where patients said they most often held the phone, lead researcher Patricia McKinney, an epidemiologist at the Leeds Institute of Genetics, Health and Therapeutics, said that the finding probably was due to many patients not accurately recalling which ear they had used most. The Swedish study, conducted by researchers at the Karolinska Institute, found an increased risk for a non-cancerous brain tumour called acoustic neuroma after 10 years of mobile phone use.

.."Der Grund warum diese Studie allerdings so groß aufgestellt wurde, ist daß bei den Langzeitnutzern- das heißt, die die ein Handy zehn Jahre oder länger benutzt haben, die Fallzahlen noch relativ gering sind. Das heißt die Aussagekraft einer nationalen Studie ist relativ klein. Und in diesem Bereich haben auch alle vier Länder bisher Ergebnisse mit einer sehr großen statistischen Unsicherheit veröffentlicht. Bei den Schweden, Dänen und Engländern gab es eher keinen Hinweis auf eine Risikoerhöhung. Bei uns in Deutschland gab es jetzt einen schwachen Hinweis auf eine Risikoerhöhung was auf jeden Fall eben dafür spricht die internationalen Ergebnisse aller 13 Länder abzuwarten."

"..und dem entsprechend muß man abwarten, ob dies unser Ergebnis jetzt von anderen Ländern bestätigt wird oder, ob dann insgesamt die 13 Länder eher das Ergebnis der schwedischen und dänischen Studie und englischen Studie bestätigen werden, daß es keine Risikoerhöhung auch unter den Langzeitnutzern gibt."

Hiermit macht Herr Doktor große Mobilfunk-Propaganda für die Mobilfunkindustrie. Die Studien aus Schweden und aus England haben sehr wohl mehrfach die deutschen Ergebnisse bestätigt. siehe unter Interphone England und Interphone Schweden. und Interphone Denmark**.
Nur die Aussagen der dänischen Studie sind für die Einschätzung der Gefahr der Langzeitnutzung der Handys, länger als 10 Jahre wegen der zu kleinen Anzahl der Nutzer mit Tumoren - zwei - nicht geeignet, aber auch diese Studie bestätigt indirekt die Gefahren der Langzeitnutzung - die Tumore bei Mobilfunknutzer sind größer als bei Nichtnutzer. siehe dänische Studie

Die Aussagen der schwedischen Studie wurden durch Meckereien der wohl gekauften Wissenschaftler über schlechte Aufstellung der Studie und danach durch die Doktorarbeit, die von ICNIRP-Verschwörer und Doktorvater Ahlbom A. zur Interphonestudie umbenannt wurde, umgedreht und weitgehend verwässert. Nicht destotrotz Sie finden sie und weitere, zum Vergleich unten über diese Seite.

Beachten Sie z.B. Berichte aus Israel von Atzmon Interphone researchers misled the media

Omega siehe "Interphone researchers misled the media - Cell phone cancer link misreported" unter: http://omega.twoday.net/

Sie beweisen, daß Dr. Lüz nicht zufällig die Tatsachen verdreht ! Das ist das Design von exBücherverbrennung, das ich schon am 10. Oktober 2004 beschrieben habe.

Deutsche Studie bezüglich Langzeitexposition der Handynutzer bestätigt Interphone Aussagen aus England und Schweden.

Drei Interphone-Studien zusammengenommen, beweisen langfristige Tumorgefahr für Handynutzer !

** "In a Swedish case control study of 159 cases of acoustic neuroma, the authors found a significant association between use of analogue cellular telephones and risk of this type of tumor (odds ratio = 3.5, 95 percent CI: 1.8, 6.6); however, there was no clear trend in the risk estimates by latency period (>1, >5, or >10 years) since first use ( 1. ). In an update of this analysis, the risk of acoustic neuroma was found to be significantly increased among persons who had used digital cellular telephones for more than 5 years and among persons who had used cordless telephones for more than 10 years (2).- Seite 282 in der dänischen Studie (Christensen et. al.

The Interphone study in Germany has found a double risk of glioma after more than ten years of mobile phone use. The group of long-term users was relatively small and part of them has been using the 450 MHz analogue system too.

The elevated risk can be the result of a statistical deficiency or an unknown cause. Therefore a press release of Bielefeld University says, mobile phone use does not increase the risk of brain tumours.

However, the elevated risk is remarkable, because it is most plausible in the group of long-term users, according to the press release. Two Interphone studies in Great Britain found elevated risks of acoustic neuroma and glioma. In both cases press releases did not mention an elevated risk. The European Interphone studies are done in 13 countries. The studies are financed partially by the Mobiel Manufacturer's Forum and the GSM Association. The German study was partially paid by the Mobilfunkforschungsprogramm of the Bundesregierung, two ministries and Mainz University. The German study was conducted by J. Schüz of the Institute of Cancer Epidemiology in Copenhagen, Denmarkt. He was also involved in the Danish Interphone study.

Using a mobile phone for 10 years or more increases the risk of ear tumours by four times, research suggests.
750-people study by exSweden's Karolinska Institute found the risk of acoustic neuroma rose by 3.9 times on the side of the head the phone is used. There was no increase in risk on the other side of the head - giving an overall rise in risk of 1.9 times.
Acoustic neuroma is a benign tumour in the auditory nerve, which can cause brain and nerve damage.

It affects one in 100,000 people. Those who had used mobile phones for less than 10 years were not at a greater risk, the team reported. Out of the 750 people who took part in the study, 150 had acoustic neuroma and of those one in 11 had used a mobile phone for at least a decade.

Professor Anders Ahlbom, from the Stockholm-based institute, told BBC News Online he was "surprised" by his team's findings. "The results show there is a relatively substantial risk and we are hoping others will follow up our research. "We do not know what is causing it but the risk certainly increases over time." He said he would not go as far as warning people not to use mobile phones.

Risk

At the time of the study only analogue mobile phones had been in use for more than 10 years. The majority of people now have digital (GSM) phones, which came on to the market in the mid to late 1990s. Some of the people who took part in the study had used both analogue and digital phones. There was no evidence to suggest solely using digital phones for 10 years increased the risk.

Dr Michael Clarke, a spokesman for the National Radiological Protection Board, the UK's advisory group, said it was a "good study from a well respected institute".

He said: "It is suggestive rather than conclusive but we will obviously take it into account when we issue guidance in the future."

And a spokeswoman for the Mobile Operators Association said: "The mobile phone industry takes very seriously questions relating to the safety of its products and is committed to addressing public concern in an open and transparent manner."

But she added: "Individual studies must be seen in the light of the total research effort into mobile phone safety. There have been other recent studies that have failed to show any link between mobile phones and tumours."

Three quarters of adults in the UK own or use a mobile phone. The mobile phone industry has always maintained there is no scientific evidence of negative effects from mobile phone use. But over the last few years experts have remained divided over the question of risk. A study by Finnish scientists in 2002 found electromagnetic radiation, which is emitted from mobile phones, affected human brain tissue. But the UK government-commissioned Stewart report in 2000 concluded there was no evidence of harm associated with using mobile phones. However, the report recommended a precautionary approach and said children should only use mobile phones in emergencies.
