Radiating the People: Worrying new claims say childhood cancer cluster has developed around Fukushima radiation zone

It’s what post-Fukushima Japan fears the most; cancer. Amid allegations of government secrecy, worrying new claims say a cancer cluster has developed around the radiation zone and that the victims are children.

In a private children’s hospital well away from the no-go zone, parents are holding on tight to their little sons and daughters hoping doctors won’t find what they’re looking for. Thyroid cancer. Tests commissioned by the local authorities have discerned an alarming spike here. Experts are reluctant to draw a definitive link with Fukushima, but they’re concerned.

“I care because I went to Chernobyl and I saw each child there, so I know the pain they went through”, says Dr Akira Sugenoya, a former thyroid surgeon. What terrifies parents most is a government they feel they can’t trust. It’s created a culture of fear; one which has led a number of women post-Fukushima to have abortions because they were worried about birth defects.

“The doctors in Fukushima say that it shouldn’t be coming out so soon, so it can’t be related to the nuclear accident. But that’s very unscientific, and it’s not a reason we can accept”, Dr Sugenoya insists. “It was disclosed that the Fukushima health investigation committee was having several secret meetings. I feel the response has been unthinkable for a democratic nation“, Dr Minoru Kamata from the Japan Chernobyl Foundation says.

Researcher: Children’s cancer linked to Fukushima radiation

TOKYO — A new study says children living near the Fukushima nuclear meltdowns have been diagnosed with thyroid cancer at a rate 20 to 50 times that of children elsewhere, a difference the authors contend undermines the government’s position that more cases have been discovered in the area only because of stringent monitoring.

Most of the 370,000 children in Fukushima prefecture (state) have been given ultrasound checkups since the March 2011 meltdowns at the tsunami-ravaged Fukushima Dai-ichi nuclear plant. The most recent statistics, released in August, show that thyroid cancer is suspected or confirmed in 137 of those children, a number that rose by 25 from a year earlier. Elsewhere, the disease occurs in only about one or two of every million children per year by some estimates.

“This is more than expected and emerging faster than expected,” lead author Toshihide Tsuda told The Associated Press during a visit to Tokyo. “This is 20 times to 50 times what would be normally expected.”

The study was released online this week and is being published in the November issue of Epidemiology, produced by the Herndon, Virginia-based International Society for Environmental Epidemiology. The data comes from tests overseen by Fukushima Medical University.

Making sense of the relationship between radiation and cancer is precarious: It’s scientifically impossible to link an individual cancer case to radiation. Looking harder with routine check-ups, like the one in Fukushima, leads to quicker discovery of tumors, inflating the tallies in a so-called “screening effect.”

Right after the disaster, the lead doctor brought in to Fukushima, Shunichi Yamashita, repeatedly ruled out the possibility of radiation-induced illnesses. The thyroid checks were being ordered just to play it safe, according to the government.

But Tsuda, a professor at Okayama University, said the latest results from the ultrasound checkups, which continue to be conducted, raise doubts about the government’s view.

Thyroid cancer among children is one sickness the medical world has definitively linked to radiation after the 1986 Chernobyl catastrophe. If treated, it is rarely fatal, and early detection is a plus, but patients are on medication for the rest of their lives.

Scientists are divided on Tsuda’s conclusions.

…

David J. Brenner, professor of radiation biophysics at Columbia University Medical Center, took a different view. While he agreed individual estimates on radiation doses are needed, he said in a telephone interview that the higher thyroid cancer rate in Fukushima is “not due to screening. It’s real.”

Conclusions about any connection between Fukushima radiation and cancer will help determine compensation and other policies. Many people who live in areas deemed safe by the government have fled fearing sickness, especially for their children.

An area extending about 20 kilometers (12 miles) from the nuclear plant has been declared an exclusion zone. The borders are constantly being remapped as cleanup of radiated debris and soil continues in an effort to bring as many people back as possible. Decommissioning the plant is expected to take decades.

Noriko Matsumoto, 53, who used to work as a nurse in Koriyama, Fukushima, outside the no-go zone, fled to Tokyo with her then-11-year-old daughter a few months after the disaster. She had initially shrugged off the fears but got worried when her daughter started getting nosebleeds and rashes.

“My daughter has the right to live free of radiation,” she said. “We can never be sure about blaming radiation. But I personally feel radiation is behind sicknesses.”

Andrew F. Olshan, professor at the Department of Epidemiology at the University of North Carolina, in Chapel Hill, noted that research on what follows a catastrophe is complex and difficult.

“Dr. Tsuda’s study had limitations including assessment of individual radiation dose levels to the thyroid and the ability to fully assess the impact of screening on the excess cases detected,” he said.

“Nonetheless, this study is critical to initiate additional investigations of possible health effects, for governmental planning, and increasing public awareness.”
