INTO THE DO-THEY don't they mobile phone brain-frying debate comes a Japanese study which concludes that using the pesky devices does not raise the risk of getting a brain tumour.
Researchers at Tokyo Women's Medical University compared 322 brain cancer patients with 683 healthy mobile phone users and found no increased risk of the three main types of brain cancer in regular mobile phone users.
They assessed levels of radiation in terms of the number of years since a mobile was first used, the average number of hours spent on the phone each day and which parts of the brain were most likely to be affected.
Professor Naohito Yamaguchi, of the Tokyo Women's Medical University, 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."
Dr Lesley Walker, Cancer Research UK's director of cancer information, isn't convinced "So far, studies have shown no evidence that mobile use is harmful, but we can't be completely sure about their long-term effects," she said. " Research is still ongoing and Cancer Research UK will continue to look for new evidence."
The study appears in the British Journal of Cancer. ยต
Exactly how many studies will have to show no-risk from mobile phones before we can be "completely sure about their long-term effects," Dr Lesley Walker ?
This is like the plethora of powerline studies done in the last century on the same classes of diseases (cancers). sigh...

You would think with our far better understanding of the mechanics of cancers biologically that this sort of thing would stop being such a big "scare". 

Cellphones do not emit any sort of ionizing radiation whatsoever. As in none. The waves emitted from a cell (or a cordless phone, or a wifi antenna, a bluetooth dongle, or insert-name-of-any-other-radio-frequency-device-you-can-think-of) are just too fat to lead to the sort of molecular damage necessary. The waves are too big. 

Having said that, mobile phones may not cause brain cancer, but text messaging does make you stupid.

... if people who talk on cell phones get brain cancer, so what exactly is the point of this study?
