Mobile phones are undeniably convenient, but that fat that they emit electromagnetic radiation means that they have at least some potential to affect individuals who use them. For a long time, the party line was that mobile phones are safe. This is a message the industry has been particularly keen to cultivate. However, at least some evidence suggests otherwise. In a blog last year (which you can read here), I wrote about a study which found that mobile phone use was associated with an increased risk of gliomas (the most common form of brain tumour) and acoustic neuromas (benign tumours that grow on the nerve responsible for hearing).

This week, I came across a newspaper report of a World Health Organization (WHO) study which raises further doubts about the safety of mobile phones. The study involved interviewing almost 13,000 from 2000-2004 over 13 countries. The study has yet to be published (it is due for publication later this year), but this report about it claims that:

6 of 8 studies found an increased risk of glioma associated with mobile phone use

One study found an increased risk of tumours of the parotid gland (a salivary gland in the side of the face near where mobile phones are held) associated with heavy mobile phone use

The results, though not entirely conclusive, clearly have concerned the WHO. Its head, Dr Elisabeth Cardis, is quoted as saying
