The on again -- off again cellular phone/brain tumor debate is on again.
Last year, the Dutch Health Council, in an overview of research from around the world, found no evidence that radiation from mobile phones and TV towers was harmful.
A four-year British survey in January also showed no link between regular, long-term use of cell phones and the most common type of tumor.
Now there is a Swedish study, released last Friday, that contradicts the conclusions of other researchers.
One group cries wolf and then another study says there is no link between cellular phone use and brain tumors.
What are we to believe?
