Do cellphones cause brain damage?

From Alex Tabarrok at Marginal Revolution.

Siddhartha Mukherjee, author of the acclaimed The Emperor of All Maladies: A Biography of Cancer, asks do cellphones cause brain cancer? Mukherjee does a good job laying out different research designs–experimental, epidemiological, retrospective and prospective case-control studies–and their potential confounds. The best extant studies find little, no, or even a small beneficial effect, and thus Mukherjee concludes that as of now the evidence remains “far from convincing.”

One less thing to worry about. So don't worry, be happy!
