This report is crap–but it is reported as a phenomenon that is associated with the non event at 3 mile island.
Let’s see if I can repeat it loud enough. A Cancer Cluster is not proof of anything, even if Jane Fonda says so.
However why not float a trial balloon when you don’t have anything to do but data dredge. Note the real incidence of the more malignant thyroid cancer is 5% and now we have a relative risk of 10%???? No, not really, rate of the Hurthle form is increased from %% to 10% in this sample, but the researchers have no information on exposure or that there was any exposure, since there was never any evidence of environmental discharge of radioactive material–so the researchers just have a variation in the rate of the cancer.
A similar sampliing and analysis might show the variation in rate of the Hurthle type cancer in another population–which we could call normal variability. They call it what?
