Radiation exposure can come from power plant accidents, fallout from nuclear weapons use, or some medical treatments. In cases that underwent surgery, the final diagnosis was based on histopathological analysis of the surgical specimen by a staff pathologist. Fine-needle aspiration biopsy. However, due in part to adoption of more stringent criteria for diagnosing thyroid cancer, the incidence rate has declined by about 2% each year since 2014.
