London, Oct 24 : Long-term mobile phone users are at an increased risk of developing cancer in later life, warns a decade-long study.

The survey of 12,800 people in 13 countries has reportedly found that heavy mobile use is linked to brain tumours.

The report, which will be published later this year, has been overseen by the World Health Organisation, reports The Daily Express.

The inquiry’s preliminary results look at whether mobile phone exposure is linked to three types of brain tumour and a tumour of the salivary gland. (ANI)
