title: Minimizing the Health Effects of the Nuclear Accident in Fukushima on Thyroids.
abstract: Because of the March 2011 nuclear accident in Fukushima, Japan, the Fukushima Prefecture initiated a thyroid ultrasound examination program. The first cycle of examinations on all children (more than 300,000) of the Fukushima Prefecture identified 116 patients as having malignant or suspected malignant thyroid nodules, and in the second cycle 59 new cases were identified. According to the available data, the thyroid cancers found by the screening are unlikely to be due to radiation, but the possibility cannot be excluded.
  The current thyroid ultrasound examination program has been detecting thyroid cancers, regardless of the cause, in all children in the Fukushima Prefecture. Fukushima Prefecture is already taking measures against thyroid cancer, even if an increase occurs in radiation-induced thyroid cancer in Fukushima Prefecture. Therefore, the urgent challenge is how to treat children with thyroid cancer found by the screening.
  At the end of each cycle, the findings must be carefully discussed with experts around the world and among stakeholders in Fukushima, and a consensus must be reached regarding whether the current program will be continued or needs improvement. In addition, the survey should be improved as an epidemiological follow-up research program. Before starting this, a consensus must be reached with the inhabitants with regard to carrying out epidemiological research for several decades. Dialogue absolutely must continue among all stakeholders to determine how best to formulate a program to deal with urgent matters and to determine the next stage of any epidemiological research.
