The jury is still out on mobile phone health risks. Picture / AP Allegations of bad science, not enough science, conflicts of interest, political inertia, scaremongering, lobbying and lawsuits: the debate about the safety of mobile phones has it all.
With more than 5 billion in use worldwide, mobile phones have become central to modern life, but could they be a health hazard?
Scientists at the Children with Cancer conference in London this week called for governments to adopt the "precautionary principle" - advising users to take simple steps to protect themselves and children from potential and not proven health risks of electromagnetic fields - especially head cancers.
They called for urgent research into new Office of National Statistics figures that suggest a 50 per cent increase in frontal and temporal lobe tumours - the areas of the brain most susceptible to the electromagnetic radiation emitted by mobile phones - between 1999 and 2009.
In Britain, MP Caroline Lucas will next week table an Early Day Motion calling for mandatory safety information at the point of sale, and for widely publicised advice, for young people in particular, to text, use headsets or corded landlines for long calls.
