Thyroid Examination: Results of the Initial Screening and the Full-scale Screening (Details of Fine-needle Aspiration Cytology)

These graphs show the age distribution, as of March 11, 2011, of examinees who subsequently had thyroid lesions diagnosed as malignant or suspicious for malignancy by fine-needle aspiration cytology, and their ages at the time of the Confirmatory Examination. So far, the situation is that thyroid cancer is not found more frequently among young children (aged zero to 5), who are considered to have higher sensitivity to radiation, than among people in the other age brackets.

These are only interim results and will be updated later.
