(On a side note: I cannot confuse "cancer rate" with anything, because that term is basically undefined and left to interpretation by individuals. It is only used by anti-nuke-kooks when applying statistical trickery.)
You'll note that a "ten-fold increase in the incidence of leukaemia in children" is quite something different than "ten-fold increase of cancer rates"
"standard dose/risk models underestimate the expected number of additional child leukemia cases by a factor of up to 10". A far cry from "cancer rates increased by a factor of 10".
