Thyroid Ultrasound Examination: Results of the Preliminary Baseline Survey and the Full-scale Survey (Details of Fine-Needle Aspiration Cytology 2)_Figure

These graphs show the age distribution, as of March 11, 2011, of participants who subsequently had thyroid lesions diagnosed as malignant or suspicious for malignancy by fine-needle aspiration cytology in the second and third Full-scale Surveys (third- and fourth-round surveys), and their ages at the time of the Confirmatory Examination. The distribution by age at the time of the disaster tends to be shifted towards younger ages compared with the results of the Preliminary Baseline Survey and the first Full-scale Survey (second-round survey), but the distribution by age at the time of the Confirmatory Examination was the same as in the case of the Preliminary Baseline Survey and the first Full-scale Survey (second-round survey).
