Mobiles 'not brain cancer risk'

2008-02-06 12:44:17

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.

We can't be completely sure about their long-term effects

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.
