The last survey result of 44 malignant cancer/suspected cancer cases among Fukushima children a few months ago was replaced by the latest report released today.
Thirteenth Prefectural Oversight Committee convened on November 12, 2013, releasing the results of the latest thyroid examination as part of the prefectural health management survey.
Total number of children examined as of September 30, 2013: 289,960
Total number of children whose initial examination results are confirmed: 225,537
(up to the August 23rd, 2013 examination)
Assessment A1 121,525 (no nodules or cysts found)
Assessment A2 102,453 (nodules 5.0 mm or smaller or cysts 20.0 mm or smaller)
Assessment B 1,558 (nodules 5.1 mm or larger or cysts 20.1 mm or larger)
Assessment C 1 (requiring immediate secondary examination)
Secondary examination includes more detailed thyroid ultrasound, blood and urine tests, and fine-needle
aspiration biopsy if warranted.
1,559 are eligible for secondary examination
1,148 have actually undergone secondary examination
897 finished the secondary examination
In summary, as of September 30, 2013, 26 thyroid cancer cases are confirmed and 32 have suspicious biopsy results. (As of July 31, 2013, there were 18 confirmed and 25 suspected cases).
During the press conference following the committee meeting, no information was given, as to the details of individual cancer cases, such as the presence of lymph node metastasis or the type of surgery done.
Shinichi Suzuki maintains that this thyroid examination was originally initiated to assess the baseline thyroid condition of Fukushima children, as there is no such epidemiological data available in Japan, with an understanding that it was not possible to obtain pre-exposure data. It is being conducted on an assumption that the effect of radiation exposure would not be obvious for at least four years after exposure, as was seen after the Chernobyl accident.
How reliable the result of the survey is under question. The doctors from the Fukushima Health Management Survey have just made a public apology for 390 errors they made in the past 5 survey results. In the mean time, it is undeniable that there has been a steady increase in incidences of thyroid malignancy among Fukushima Children.
