Interphone study says no risks? The results are far from conclusive.

http://www.ncbi.nlm.nih.gov/pubmed/20483835 - "CONCLUSIONS: Overall, no increase in risk of glioma or meningioma was observed with use of mobile phones. There were suggestions of an increased risk of glioma at the highest exposure levels, but biases and error prevent a causal interpretation. The possible effects of long-term heavy use of mobile phones require further investigation."
This conclusion has sentences that contradict each other. E.g. Heavy long-term use has higher negative numbers, compared to the "normal use" that causes "no increased risk" ?!
Claims that interphone found any statistically significant risk increase due to the use of cell phones is not backed up by the data in any way, shape, or form. (But this, of course, doesn't mean there is no risk, but that we haven't seen it. Future studies could find such a risk, as unlikely as that may be.)
This makes no sense. While it's easy to argue that cell phones are safe because of non-ionizing radiation, that's now how science works. The reason we feel that cell phones are safe is that we have 25 years of evidence showing no statistically significant link between cell phone use and cancer.
Even if there's a magical field that a cell phone produces that causes cancer (something we can't detect in any way), we'd still detect that cancer with a higher rate than in a population that doesn't use cell phones, or uses them with a lower frequency.
