I didn't say there was a step function at the ten year threshold
and I'm certainly not going to type in the entire article. It is
much more likely that it is a ramp function roughly emerging from
the average after around ten years of use.

Of course a proportional function is more likely although perhaps not
linear however your statements that "No tumors were associated with less
than 10 years of cellphone use" and "People with more than 10 years of
cellphone use suffered twice as many tumors as non-cellphone users"
describes a step function at ten years {t = 1 for y 10 and t = 2 for y
10, where y is the number of years and t the base rate for brain
tumours in a non-mobile phone using control group). Given this
simplistic step function I must have doubts about the accuracy of the
study that lead to such a conclusion

I do not expect you to type in the entire article, but you only stated
"No tumors were associated with less than 10 years of cellphone use"
which provide no information about any association after ten years.
