Mobile phone risk revealed

Long-term phone use doubles occurrence of rare tumour.

"We were surprised about the results, but the outcome is quite clear," says Anders Ahlbom, an epidemiologist at the Karolinska Institute, who was involved in the study.

"We are now convinced of the quite strong risk due to the use of mobile phones, and we are waiting for confirmation from the other research groups," says Ahlbom.
