This is just one study and there are baffling results if you look at the data. For example, there's no good explanation for why the middle exposure group often had ZERO cancer (just like the control), with all the problems in the high & low exposure group. That says to me that the random variance is high enough to swamp out the signal here. This also has to be weighed against all the studies that found no link. I strongly expect that future studies will fail to replicate these results.
