Major Cell Phone Radiation Study Reignites Cancer Questions

The results do not seem all that convincing to me, even though the authors seem to be saying that the results are significant.

But it's not like a significant percentage got tumors while the controls did not. The differences are in the order of a few percent. Probably worth a closer look, but does not seem to me you can draw some major conclusion from this.
