The WHO has said there MAY be a link with tumours. I know two prominent NA docs, one is a bigwig at NYU, a relative, who say cell phones cause tumours and they don't need any more studies.

I didn't know that the WHO were still performing, but leaving that aside, there has been at least one, maybe more, threads here on this subject.

If cell phones cause tumors, it is due to processes unknown to science, which is to say, possible but unlikely.

The frequencies known to be hazardous are MILLIONS of times shorter than cell phone frequencies. They are hazardous because they knock electrons out of their orbits, which cell phone frequencies do not.

I lived in Germany for nearly ten years, during which time I used a cell phone exclusively, and frequently. No tumors. BUT...

Every time I wash my car it rains. Car washing causes rain, I don't need any more studies either.
