By comparison, the total incidence of cancers among males aged 0-14 in SEER areas in the USA (representing 28% of the population, per their website) is 149.5 per million, and for females aged 0-14 is 128.7 per million. Thyroid carcinoma is at 0.9 per million in males, and 2.9 per million in females[1]. So, while they had a higher rate than in the USA even before 1970 (4 per million for males and 8 per million for females), I would be extremely doubtful that the increase in numbers is just due to an increase in diagnosis because doctors are expecting to see cancers.
