Thyroid cancer
A Papillary carcinoma B Normal thyroid tissue
C Nodular tumor
A:  A papillary structure with atypical cells and the proliferation of tumor cells is evident (papillary carcinoma).
B:  Normal thyroid tissue (colloid follicles show a regular arrangement).
C:  A nodular tumor is evident in the cervical region.
D: Excess relative risk of thyroid cancer(1958-1987)
Excess relative risk
The increase in excess relative risk at 1 Sv for all ages was 1.15.
The excess relative risk was higher in people who were young at the time of bombing than in those who were old at the time of bombing.

E: Thyroid disease in the Nagasaki atomic bomb survivors
Thyroid disease
Solid nodules of the thyroid (thyroid cancer, adenoma, adenomatous goiter, nodules without histological diagnosis) were significantly more frequent among the atomic bomb survivors than among non-exposed persons, and it is known that the number of cases was higher the higher the dose and the lower the age at the time of bombing.
Antibody-positive spontaneous hypothyroidism was significantly more frequent among the atomic bomb survivors than among non-exposed persons. Moreover, the frequency reached a peak at a dose of 0.7Sv, which was lower than that in cancer cases.
