チェルノブイリのときも、「甲状腺ガンは探そうと思えばたくさん出てくる」と言い張るバカどもが多かった。
それに対して、山下センセイはきっぱりと「ベラルーシの甲状腺ガンは潜伏ガンなどではありえず、放射能が原因だ」と言っている。
バカ安全厨ども、どう答える？
The relationship between the Chernobyl accident and thyroid cancer has not been established.
In fact, there is some skepticism about this relationship, one being that the detection of occult cancer
as a result of the intensive surveillance in the Chernobyl area might have contributed to the dramatic increase
in childhood thyroid cancer around Chernobyl. Nevertheless, a histological review of thyroid cancers resected
between 1986 and 1991 negated the possibility of an increase in the detection of dormant or occult cancer by meticulous screening,
since most cases were aggressive and exceeded 19 mm in mean diameter. Also, occult thyroid carcinoma is observed rarely at autopsy
in adolescents. Recently, the incidence of occult thyroid carcinoma in Minsk, Belarus was investigated in 215 autopsy cases aged 19 to 88 years.
Carcinoma was found 20 cases (9/3%). All patients were over 40 years old, and all except one of the tumors were papillary carcinoma smaller than 5 mm in diameter.
In our series, the mean tumor size was 16 mm, with a minimum diameter of 6mm. These facts suggest that the increase in childhood thyroid cancer is due,
not to the detection of occult carcinoma, but to other factors such as radiation exposure.
