The expert group convened by the International Agency for Research on Cancer (IARC) recommended against population thyroid screening following a nuclear accident.1 At the population level—meaning all residents in a geographic region are invited for screening without regard to radiation exposure—the harms of thyroid screening were deemed to outweigh the benefits. Screening would lead to overdiagnosis of a large reservoir of clinically insignificant disease, and would be unlikely to improve outcomes for radiation-induced thyroid cancers, which are highly curable with standard therapy.
