'No link between mobile phones and cancer'

Even though mobile telephone use soared from the 1990s , brain tumours did not become any more common, the researchers reported in the Journal of the National Cancer Institute.

Over the years, various activist groups and researchers have raised concerns about a link between mobile phones and several kinds of cancer, including brain tumours, although years of research have failed to establish a conclusive connection, the Reuters report claims.

"We did not detect any clear change in the long-term time trends in the incidence of brain tumours from 1998 to 2003 in any subgroup," Isabelle Deltour of the Danish Cancer Society wrote.

Deltour's team analysed annual incidence rates of two types of brain tumour – glioma and meningioma – among adults aged 20 to 79, from Denmark, Finland, Norway, and Sweden, from 1974 to 2003. This represented virtually the entire adult population of 16 million people, the researchers said. The Scandinavian countries all have comprehensive cancer registries that record details of known cancer cases.

"In Denmark, Finland, Norway, and Sweden, the use of mobile phones increased sharply in the mid-1990s; thus, time trends in brain tumour incidence after 1998 may provide information about possible tumour risks associated with mobile phone use," the researchers wrote.

Over the 30 years, nearly 60,000 patients were diagnosed with brain tumours. While the team did see a small, steady increase in brain tumours, this started in 1974, long before mobile phones arrived.

"No change in incidence trends were observed from 1998 to 2003," the researchers noted. This would have been when tumours would start showing up, assuming it took five to 10 years for one to develop, they said.

Most scientific studies show no association between mobile phone use and brain tumours, and rearchers trying to find a connection have failed to find any biological explanation for how a mobile phone might cause cancer, according to the Reuters report.

"Because of the high prevalence of mobile phone exposure in this population and worldwide, longer follow-up of time trends in brain tumour incidence rates are warranted," the research team cautioned.

And that will be the last word on the subject until some other "chicken little" yells, "The sky is falling!" and then it will start all over again. Sad.

mobile phones do have a effect on you though, even if not brain cancer.

i always get a very peculiar pain in my ears which spreads into a head ache on the side of my head which is exposed to the mobile phone.

it only happens sometimes, but it always happens if i speak on the phone for more than about 20 minutes.

my father in law used to get a rash from the first mobile phones on his cheeks. so no chicken little there, i m afraid.

I wonder if Ericsson was a contributor to this "research". Vodaphone help funded similar research with identical findings in the UK stating that there was no link.

A Reuters article from 2006 states an independent Swedish research finds a link not limited to mobile phones but also cordless phones as well.

["]The use of mobile phones over a long period of time can raise the risk for brain tumors, a new Swedish study said on Friday, contradicting the conclusions of other researchers.

The Dutch Health Council, in an overview of research from around the world, last year found no evidence radiation from mobile phones and TV towers was harmful. A four-year British survey released in January showed no link between regular, long-term use of cell phones and the most common type of tumor.

However, researchers at the Swedish National Institute for Working Life said they looked at the mobile phone use of 905 people between the age of 20 and 80 who had been diagnosed with a malignant brain tumor and found a link.

"A total 85 of these 905 cases were so-called high users of mobile phones, that is they began early to use mobile and/or wireless telephones and used them a lot," the study said.

"The study also shows that the rise in risk is noticeable for tumors on the side of the head where the phone was said to be used," it added.

Kjell Mild, who led the study, said the figures meant that heavy users of mobile phones, for instance of who make mobile phone calls for 2,000 hours or more in their life, had a 240 percent increased risk for a malignant tumor on the side of the head the phone is used.

"The way to get the risk down is to use hands-free," he told Reuters.

He said his study was the biggest yet to look at long-term users of the wireless phone, which has been around in Sweden in a portable form since 1984, longer than in many other countries. ["]


It's too bad that the Swedish National Institute for Working Life was AFAIK was closed within a year of the researchers announcement by a decision of the Swedish government party.


The dozens of contradictory studies of links to cancer from longterm RF/MW exposure are no different than the countless contradictory studies that apply to prescription medicine and chemical safety. At the end of the day the power of money and business wins and the consumer and the (environment) will always suffer the long term consequences.

I agree with Broklyn Bjorn. And thank you for those useful links.

I do wish newspapers when reporting would provide the info on where the funding comes from.

Thank you Broklyn Bjorn for sharing with us the truths.

First official reaction against mobile phones camne from

Salzburg. Sorry, I have no details. Important data is in the

book "Black and White" by Lind. (Swedish Assoc. for protection from radiation. their contact is in the book.)

Interesting that they noticed an increase since 1974. Wasn't that around the time microwave ovens became widespread in Scandinavia?
15:09 December 6, 2009 by Keith #5083
Have any of these Scandinavian researches factored in the 'Chernobyl effect'? I recall that for a very long time sheep in North Wales were barred from sale for human consumption because of the pollution from Chernobyl. What is the European rate of increase for all 'radiation' cancers and how does that relate to increases/decreases in brain tumour?

Or has everyone forgotten about Chernobyl???

Incidentally to the 'poor us, misused by capitalism brigade', - you can always say 'NO' and not buy or use the products.
