Mobile phones do not raise the risk of brain tumors

Mobile phone use does not raise the risk of brain tumours, a Japanese study suggests.

The research is the first to look at the effects of hand set radiation levels on different parts of the brain.

Tokyo Women's Medical University found no increased risk of the three main types of brain cancer among regular mobile phone users.

The study, comparing 322 brain cancer patients and 683 healthy people, appears in British Journal of Cancer.

The cancer patients had one of the three most common types of brain tumour - glioma, meningioma or pituitary adenoma.

The researchers rated each subject according to how many years they had been using a mobile phone, and how long they spent talking on it each day.

They studied the radiation emitted from various types of mobile phone, and placed them into one of four categories relating to radiation strength.

And they also analysied how each phone was likely to affect different areas of the brain.

Lead researcher Professor Naohito Yamaguchi said: "Using our newly developed and more accurate techniques, we found no association between mobile phone use and cancer, providing more evidence to suggest they don't cause brain cancer."

Contradictory findings

Previous research on the safety of mobile phones has produced contradictory results.

However, most have suggested no association with an increased risk of cancer.

The largest study to date, involving 420,000 people, failed to find any evidence of a cancer trend even after 10 years of use.

Dr Lesley Walker, of the charity Cancer Research UK, said: "So far, studies have shown no evidence that mobile use is harmful, but we can't be completely sure about their long-term effects.

Scientists around the
world have been monitoring the effects of radio-frequency fields on
human health for around 60 years.

Public concern over the
safety of mobile phones has grown as more and more adults and children
rely on them for everyday communication, although the evidence to date
has given the technology a clean bill of health.

Despite an
explosion in mobile phone use around the world since the 1980s, the
number of cases of brain cancer has hardly changed.

new study coming from Japan says that holding a cell phone to your head
and gabbing all day long will not increase your risk of brain cancer.
It may, however, increase your risk of becoming a social outcast,
getting into car accidents and walking into a light post.[/q]

this latest study confirms yet again that cell phone's don't cause
cancer. These findings echo the results of some studies, while
contradicting the results of others. The study did not highlight the
effects of continued cell phone use on social status, financial status,
employment status, nor how it effects your cholesterol. It also failed
to point out the other ways in which cell phone use puts your life at
risk.

You can rest assured that constantly talking on your
cell phone will distract you from everything going on around you. So if
you're talking while driving, don't be surprised if you suddenly find
yourself upside down staring at a fire hydrant. If you're talking while
walking on crowded city sidewalks or on crammed city buses, be prepared
for people to offer you unsolicited advice on your love life, cheer you
on when you dump your significant other for cheating, and pick you up
off the sidewalk when you walk into a street sign. Lastly, if you're
talking incessantly while at work, don't be surprised if your coworkers
dump a steaming pot of coffee on your head.[/q]

A
1,256-person study in the U.K. suggests that a third of people would
not give up their cell phones for about $2 million (or 1 million
pounds), and more than half of 16- to 24-year-olds would rather give up
tea, coffee, chocolate or sex than their phones.

Thanks for the flag! I find this study to be a very complete one, how they studied the radiation emitted from various types of mobile phones and how the phones could affect different areas of the brain if they did at all, I had a pituitary adenoma back in 1999 and had never used a cell phone before.
