Giant study to examine mobile phone cancer risk

Thousands of people are to be studied over the course of 20 or 30 years to see if the long-term use of mobile phones increases the risk of developing brain tumours and other medical disorders, as part of the largest ever study into the subject.

At least 250,000 mobile phone users will be monitored as part of the multi-million-pound Cohort Study on Mobile Communications (Cosmos), which aims to settle the debate over whether there are any serious health risks from using the devices once and for all.
