Thyroid Examination: Results of the Full-scale Screening (2nd Examination)

These are the interim results of the Full-scale Screening, which was the second round of the Thyroid Examination.

Examinees diagnosed as Grade A in the Primary Examination accounted for 99.2% of the total, while those diagnosed as Grade B accounted for 0.8%. Most of those diagnosed as Grade A2 had cysts of 20 mm or smaller and those diagnosed as Grade B had nodules of 5.1 mm or larger. This tendency was the same as that observed in the Initial Screening.

In the Confirmatory Examination, as a result of fine-needle aspiration cytology, 71examinees were diagnosed that their tumors were malignant or suspicious for malignancy.
