show that thyroid cancer is suspected or confirmed in 137 of those children
Elsewhere, the disease occurs in only about one or two of every million children per year by some estimates."
Why do you include 'suspected' cases? How about splitting up those two completely different diagnoses? If it is 1 confirmed and 136 suspected, that would change the conclusion of this study, since it could potentially put it more in line with the estimates. Also, you would need the results of the same ultrasound checkups on a few hundred thousand kids living outside Fukushima to really determine if there is an increased risk of cancer or not. Going by some vague estimates isn't as accurate.
