A child diagnosed with thyroid cancer after the Fukushima nuclear accident is missing from government checkup records, an aid group said Friday, raising questions about the thoroughness and transparency of the screenings.
Japanese authorities have said that among the 184 confirmed and suspected cases of thyroid cancer in Fukushima, no one was under age 5 at the time of the 2011 meltdowns. They’ve said that suggests the cases are not related to nuclear-plant radiation, as many were after the 1986 Chernobyl disaster.

That case is not listed in data from Fukushima Medical University, which is overseeing thyroid-cancer screening and surgeries and had treated the child.

The university has been carrying out ultrasound screenings of some 300,000 youngsters in Fukushima 18 and younger at the time of the nuclear accident. It has repeatedly said it stands behind its data but declined to comment on individual cases, citing privacy concerns.
Seisho Tanaka, a spokesman for the screenings, said those who may have had tested negative could have developed cancer afterward and sought medical treatment outside the screening process. He declined to comment further.
The officials have argued the Fukushima cases are popping up because of “a screening effect,” meaning the meticulous testing uncovered cases that would not be known otherwise.
[…]“It is very puzzling how they would not want to come forward with the case,” she said, adding of the Fukushima cases and radiation: “There is no reason to outright deny the link.”[…]
