Thyroid cancer at ages 0 and 2 at the time of the nuclear accident-Health survey in Fukushima Prefecture Posted by: ourplanet Posted on: Thu, 01/14/2021 –00:46 http://ourplanet-tv.org/?q=node/2537 (Japanese only)
(Translated from Google) The “Prefectural Health Survey” Review Committee was held in Fukushima City on the 15th to discuss the health survey of Fukushima citizens following the accident at the Fukushima Daiichi Nuclear Power Plant. For the first time, it was discovered that two infants, a 0-year-old girl and a 2-year-old girl at the time of the accident, were diagnosed with thyroid cancer.
This time, the result of the fourth round of thyroid examination until June last year was newly announced. The number of children diagnosed with suspected thyroid cancer by fine needle cytology increased by 6 from the previous time to 27, and the number of children who underwent thyroidectomy increased by 3 from the previous time to 16 children. Up to now, 252 patients have been diagnosed with thyroid cancer or suspected thyroid cancer from prior examination, of which 203 have undergone thyroid surgery. 202 people, excluding one, were confirmed to have thyroid cancer.
In the fourth round of examination, it was found for the first time that a girl who was 0 years old and a girl who was 2 years old at the time of the accident were diagnosed with thyroid cancer. Since the age of the examination is not the actual age but the grade, the ages at the time of the examination are 9 years old (3rd grade of elementary school) and 11 years old (5th grade of elementary school), respectively. According to the previous test results of 27 patients, 5 patients had “A1 judgement” without nodules or tumors, and 16 people had “A2 judgement” with nodules of 5 mm or less or cysts of 2 cm or less, 5 mm or more. 5 people had a “B-judgement” with nodules or cysts of 2 cm or more, and 1 had not been examined. He had the smallest tumor size of 6.1 mm and the largest tumor was 29.4 mm.
What stands out in the results of the fourth round of examination is the high dose of radiation for people diagnosed with thyroid cancer. Of the 27 patients diagnosed as suspected of being malignant by fine needle cytology, 11 patients (40.7%) who submitted the basic survey questionnaire had an exposure dose of less than 1 mSv in 2 patients (18.1%) 4 months after the accident. The number of children exposed to 2mSv or more was the highest, with 4 (36.3%) from 1mSv to 2mSv and 5 (45.5%) from 2mSv to 5mSv. In particular, the two boys who were five years old at the time of the accident were both over 2mSv.
According to the results of the basic survey of all Fukushima residents, 62.2% are less than 1mSv, 31.6% are from 1mSv to 2mSv, and 5.5% are from 2mSv to 3mSv. Very different.
To review the mass examination at school At this review committee, a major shift was made to reviewing simultaneous examinations at schools. The test, which has found more than 200 people with thyroid cancer, raises the theory of “overdiagnosis” among experts who deny the effects of radiation exposure, saying that they are finding thyroid cancer that they do not have to find. There is a growing opinion that the mass examination at school should be reviewed.
Based on these opinions, the review committee decided to conduct an interview survey at schools in the prefecture on August 31st last time. This time, there was a report on the results of a survey conducted by the prefecture at 26 elementary and junior high schools and high schools in the prefecture.
At many schools, thyroid examinations were performed during class hours, criticized by Shoichiro Tsugane, a member of the National Cancer Center, saying, “You can’t take this without a strong will.” “The benefits of the test are not except that you can be reassured when you get negative. The discovery of thyroid cancer has little benefit in avoiding death or poor quality of life, especially when you are diagnosed with thyroid cancer. “I think it will be a huge disadvantage for those who do,” he said. “Thyroid examination in a group of asymptomatic healthy people is not desirable. I asked him to stop the mass examination at school. ..
In addition, Professor Toshiya Inaba of Hiroshima University also cut out at the school examination that “they are left behind” and said, “Parents are not worried. The school rents the venue. The prefectural medical college has an inspection. I understand each position well, but in the end, it is the people who are left unattended. ” He emphasized that the prefectures and medical colleges that are the subjects of the survey should explain more to children and students the significance of the test and the fact that it can be rejected.

In response, Professor Satoshi Tomita of Fukushima University argued head-on. He criticized that “many Fukushima residents have anxiety about their health” and that members of the Prefectural Health Investigation Committee, especially members outside Fukushima Prefecture, are calling for the cancellation or reduction of examinations. He said that thyroid examination is a way to relieve the anxiety of Fukushima residents, “the anxiety of Fukushima residents, especially those with children, is left behind.” “It is dangerous to go in the direction of reduction easily.” “Thinking” was pointed out.
Ikuko Abe, chairman of the Fukushima Clinical Psychologists Association, who also lives in Fukushima Prefecture and has a close relationship with schools, agrees with this, saying, “I agree with Professor Tomita’s opinion.” “Given the anxiety about radiation that Fukushima residents have, thyroid examinations are very reassuring,” she said. “Reducing or eliminating the examinations still takes the opposite position. I want you to do it. “
What caught my eye in the discussion was the presence of Katsushi Tahara, director of the Ministry of the Environment’s Health and Welfare Department. The members of the review committee from the Ministry of the Environment have not said much, but have played a role in important aspects of policy change. This time too, Mr. Tahara considers the fact that the school is cooperating with the implementation of the examination, such as encouraging households whose delivery to Fukushima Medical University is delayed to submit again when the deadline has passed. About 30% of the children undergoing medical examinations at school were asked intensively about this point, such as confirming that the school side took over the collection of consent forms.
To conduct hearings with the person to be inspected Following a survey of the school, the prefecture proposed to have a place to hear directly from the children and students who had been inspected. Questions were raised about the representativeness of the interviewees, and there was an opinion requesting a quantitative survey such as a questionnaire, but the prefecture’s proposal was approved because the survey took too long.
Regarding this “interview survey,” there was a harsh debate over the neutrality of the content, such as the opinion that a pilot study was unavoidable and that the voices of patients diagnosed with thyroid cancer should also be heard. With the strong push back of the constellation chairman, it was decided that the selection of the target audience and the holding method would be left to the chairperson and the prefecture. The results will be reported at the next meeting.
In response to the further shift to reviewing mass screening at school in this “interview,” Chiba parent and child of the “thyroid cancer support group Hydrangea Association” that supports families with thyroid cancer said, “Accident Among the 0-year-old and 2-year-old children at that time, a child with thyroid cancer appeared and my chest hurts. Thyroid cancer also has recurrence and metastasis, and early detection and early treatment are beneficial for the child. Given that the cancer was found in a school test, there can be no argument to eliminate the school test. ” The group has made offers to the prefecture three times in the past and opposes the reduction of inspections.
