This looks like the last thing left to worry about, but you still have to try quite hard. As far as the International Agency for Research on Cancer is concerned, evidence linking mobile phones with any type of cancer is “inadequate” – except in the case of two brain cancers, glioma and acoustic neuroma, where it is merely “limited”. As a result, it does place phones on its extremely long list of “possible” cancer-causers (along with kimchi, coffee and aloe vera). However, a huge Danish study looking for cancer links among 420,000 people found none in 2006, even among those who had used mobiles for a decade. Furthermore, phone use has gone from nought to billions in the past 20 years, so surely you would expect to see more brain cancer around? But we don’t.
