The study compared 1,617 patients with brain tumours with a group of 1,470 free from brain tumours to investigate the effects of mobile phone use.

The researchers found
(a) A 30% increase in brain tumours on the same side of the brain that was used during cell (mobile) phone calls was observed.
(b) There was a 4.4 fold increase in non-malignant tumours in cell (mobile) phone users.

This paper addressed the following question: is there evidence for an association between long-term cell (mobile) phone usage and the risk of developing a brain tumor?

The researchers found 11 studies in which statistics were available where users had being using their phones for a minimum of 10 years

The study found that cell (mobile) phone use approximately doubles the risk of being diagnosed with a brain tumor on the same ("ipsilateral") side of the head as that preferred for cell phone use.
