According to Japanese media reports, Fukushima Prefecture carried out thyroid examinations for about 380,000 children in the county after the nuclear accident. So far, 159 people have been diagnosed with cancer, and 34 people are suspected of having cancer. Among them, they are diagnosed with thyroid cancer. Of the 84 patients in Fukushima who underwent surgery, about 10% of the patients had cancer recurrence and had undergone surgery again.
On February 28, the NPO corporation's '3·11 Thyroid Cancer Children's Fund' (in Tokyo), which supports patients with thyroid cancer, was informed that 84 people were diagnosed with thyroid cancer and undergo surgery after the Tokyo Electric Power Fukushima Daiichi nuclear accident. About 10% of the patients in Fukushima Prefecture had cancer recurrence and had undergone surgery again.
Eight people were 6 to 15 years old at the time of the accident. Experts said: 'I don't know more about thyroid cancer in children. Need to continue checking.'
Fukushima Prefecture carried out a thyroid examination for about 380,000 children in the county after the nuclear accident. Up to now, 159 people have been diagnosed with cancer, and 34 people are suspected of having cancer, but no data on recurrence has been disclosed.
As of the end of January this year, the fund issued medical expenses to 111 patients with thyroid cancer in and out of Fukushima Prefecture based on medical details and self-declaration. Eight out of 84 people in Fukushima Prefecture were relapsed due to cancer. He underwent surgery again, 1 year to 4 years and 4 months from the initial surgery.
Yoshida Akira, former chairman of the Japanese Society of Thyroid Surgery, said: 'In adult patients with thyroid cancer, about 10% of them will relapse in lymph nodes in 10 years, so this data is a bit large.'
Thyroid secretion promotes metabolism and development of hormones, which are located in the throat tissue. It is said that radioactive iodine accumulation is carcinogenic. In 1986, a few years after the accident of the Chernobyl nuclear power plant in the Soviet Union, the number of children with thyroid cancer increased.

Fukushima children with high incidence of thyroid cancer, the Japanese government has no response
Singapore’s Lianhe Zaobao reported that Tsuda Minho, a professor at Okayama University’s graduate school in Japan, pointed out that 'Fukushima’s four years have the same thyroid cancer as children after the Chernobyl nuclear accident, but there is no such thing in Japan. Any preparation. '
At the end of 2015, Tsuda Minsuke and others published a paper in the international medical journal Epidemiology, which pointed out that the incidence of thyroid cancer in children in Fukushima Prefecture was the national average in Japan due to the leakage of a large amount of radioactive materials in the Fukushima nuclear accident in 2011. 20 times to 50 times.
So far, the Japanese government does not recognize the causal relationship between thyroid cancer and nuclear radiation.
In an interview with the media a few days ago, Tsuda said that the Japanese government should take appropriate measures to this end, but it did not attract the attention of the Japanese government and Fukushima. Instead, it caused many rebuttals and criticisms.
The Fukushima County People's Health Research and Research Committee believes that at this stage, 'unimaginable' the high incidence of thyroid cancer is affected by nuclear accidents, including the improvement of screening accuracy, although it is not necessary to treat but also diagnosed as thyroid cancer. Over-diagnosis', as well as a centralized examination led to the discovery of a large number of patients.
For these rebuttal opinions, Tsuda Minsho responded with professional research methods and objective and comprehensive data. He believes that even if the diagnostic accuracy is improved and 'over-diagnosis', at most it is two or three times or six or seven times the difference. The situation in Fukushima is far beyond the statistical error range.
On January 22 this year, the International Society for Environmental Epidemiology sent a letter to the Japanese government expressing 'anxiety' about the high thyroid cancer findings in children in Fukushima. The Japanese government and Fukushima Prefecture were asked to conduct detailed investigations and take more measures to clarify nuclear accidents and thyroid gland. Causal relationship between high cancer incidence. The International Society for Environmental Epidemiology said that it can be used as an expert organization to support Fukushima's related investigation activities.
The Japanese Ministry of the Environment responded by saying that the letter from the International Society for Environmental Epidemiology can be used as a reference, but the 'continuous tracking investigation' required by it is a measure that has been implemented in Fukushima Prefecture.
