Cellphones linked to brain tumours (again)
Using a cellphone for more than a decade can double the risk of some types of brain tumours, Swedish researchers said Tuesday. The Vancouver Sun reports.
"Dr. Lennart Hardell and scientists at the University Hospital in Orebro, Sweden said their analysis of previous studies shows "a consistent pattern of increased risk for acoustic neuroma and glioma."
Acoustic neuromas are benign growths on the nerve linking the ear to the brain, while gliomas are malignant, difficult-to-treat tumours of the brain and nervous system. The researchers also found that the greatest risk of developing a tumour is on the side of the head where the phone was held.
Hardell and his team identified 18 studies of brain tumour risk among long-term cellphone users, 11 of which provided data for 10 years or longer."
