Latest study from Japan
press release states "Japanese study clears mobiles of brain
cancer risk" .
This is rather a far-fetched statement
and one can only be suspicious of the motives. One study can
never alone be "proof".
In September 2007 a pooled analysis
of the 11 existing studies into brain tumours and phone use over 10
years was made.[i]
The scientists found that for tumours
on the side of the head where the phone is held people were twice as
likely to get a glioma, and two and a half times more likely to get
an acoustic neuroma Hardell and Mild (on the MTHR) from Sweden who
carried out the
analysis have also conducted their own
independent studies into long term use, which show for over 2000
hours use the risk increases five times on the same side of the head
where the phone is held.
In September Professor Mild told The
Independent on Sunday: "I find it quite strange to see so many
official presentations saying that there is no risk. There are strong
indications that something happens after 10 years." He also said
that mobiles should not be given to children, whose thinner skulls
and developing nervous systems make them particularly
vulnerable.
Interestingly, this advice was given to French
parents by the French Health Ministry in December 2007 [ii] after the
release of an Israeli Interphone study on salivary gland tumours
showed a 50% increased risk on the same side as the phone was held.

"The time is past when it
could be said that this technology does not causedamage; apparently
it damages health," said Dr Sadetzki [iv] According to Sadetzki,
director of the Gertner Institute for Epidemiology and Health Policy
Research at Sheba Medical Center, Tel Hashomer, current regulations
do not relate to cancer as caused by radiation but to the health
risks posed by the instrument heating up.Dr Sadetzki also called for
children¹s use to be limited.
There was no press release about
this Industry funded research presumably because it showed negative
effects. However the large study was conducted in 16 countries and
studied 466 patients and 1266 controls.
In January more
research funded by the MMF found that radiation from mobile phones
delays and reduces sleep, and causes headaches and confusion.

Again there was no release on the news wires since this
research had found adverse effects despite that it was performed at 2
blue-chip universities in the USA and Sweden.. Likewise it was only
reported by the mainstream media in the UK.
It is hard to
comment on this new Japanese study since there is as yet no access to
the paper however The Guardian seem to have been able to get an
advanced copy. This study needs to be put into context when it is
made available.
Update: The Guardian have said that
this study was sponsored by Cancer Research but in fact the study
said it was entirely funded by the Japanese Government and Mobile
Phone industry. The
Guardian got it wrong ."The study, funded by Cancer
Research UK, was published yesterday in the British Journal of
Cancer.'
In fact The study conducted in Japan
was fully funded by the Ministry of Internal Affairs and
Communications of Japan (the equivalent of OFCOM in the UK) with the
grateful cooperation of the surgeons and the staffs of the
participating institutions. Read
Here "A non-significant increase in OR among glioma patients
in the heavily exposed group may reflect recall bias."
A recent report on Australian TV gives
the alarming statistic that brain tumours in children have risen 21%
in the last 10 years and are now the number one cause of death in
children. [vi]
The Stewart Report warned back in 2000
that children should only use mobiles for emergencies. This needs to
be enforced by the government.
Note the Interphone studies are industry funded and concentrate on short term users.
Interesting that this Japanese study was only released at 6pm on Tuesday 5th February but by just after 7.30pm the story was already written up on The Guardian web site to be printed on Wednesday. The study is not available online and yet The Guardian seem to have read it.
It is interesting to note that The Guardian chair talks on phone risk for MP¹s paid for by the Mobile Operators Association.
They are also promoting WiFi in schools despite The Chairman of the HPA¹s doubts and no safety testing.
For more information on The Guardian involvement please read Martin Walker¹s recent essays.

Cellular Phone Use and Risk of Benign and Malignant Parotid Gland Tumors Nationwide Case-Control Study Published 6th Dec 2007

"The objective of this nationwide study was to assess the association between cellular phone use and development of parotid gland tumors (PGTs).
The methods were based on the international INTERPHONE study that aimed to evaluate possible adverse effects of cellular phone use.
For ipsilateral use, the odds ratios in the highest category of cumulative number of calls and call time without use of hands-free devices were 1.58 (95% confidence interval: 1.11, 2.24) and 1.49 (95% confidence interval: 1.05, 2.13), respectively. The risk for contralateral use was not significantly different from 1. A positive dose-response trend was found for these measurements. Based on the largest number of benign PGT patients reported to date, our results suggest an association between cellular phone use and PGTs.
