And from this article,

here is a quote that says it all:

Fortune magazine asks: If cell phones caused brain cancer, then why don’t we face an epidemic now? To those who understand the long latencies involved, the absence of a general brain tumor epidemic at this time provides no comfort. Survivors of the atomic bombs that fell on Japan experienced no increase at all in brain cancer until four decades after the war’s end. Cell phones were not heavily used until quite recently. Three out of every four cases of brain cancer occur in someone over age 60 — a group that had not used cell phones extensively even a decade ago. In contrast, every major study ever conducted has found that those who use cell phones half an hour a day or more have a doubled risk of brain cancer, and those who began using cell phones as teenagers have four to five times more disease in less than 10 years.

But we can easily see that the overal incidence of brain cancer is not increasing as you would expect if cell phones caused cancer.

I realize you will dismiss the article, but post it for the benefit of any readers stumbling upon this. Cheers.

Dave, I could show you reports from people who attribute their brain cancer to cell phone use of ten some years exist, but you would dismiss them as anecdotal, so what’s the point? The truth is brain cancer takes time to develop, grow and become symptomatic. But you should be happy because we have a perfect sample that should meet your criteria for “hundreds (preferably thousands) of test subjects to get trustworthy numbers” – the general population.

(note: thanks for including my point of view instead of only people who agree with you. Take care.)
