Journal ArticleDOI
Incidence of female breast cancer among atomic bomb survivors, Hiroshima and Nagasaki, 1950-1990.

TL;DR: A modified isotonic regression approach, requiring only that ERR1Sv be monotonic in age, provides a fresh perspective indicating that both e and a are important modifiers of dose response.
Journal ArticleDOI
Incidence of female breast cancer among atomic bomb survivors, 1950-1985
TL;DR: This a posteriori finding, based on 27 exposed, known-dose, early-onset cases, suggests the possible existence of a susceptible genetic subgroup among atomic bomb survivors, and further studies are suggested to determine whether such a subgroup exists.
Journal ArticleDOI
Breast Cancer Risk From Low-Dose Exposures to Ionizing Radiation: Results of Parallel Analysis of Three Exposed Populations of Women
TL;DR: Three populations of women exposed to ionizing radiation: survivors of the Hiroshima and Nagasaki atomic bombs, patients in Massachusetts tuberculosis sanitoria who were exposed to multiple chest fluoroscopies, and patients treated by X-rays for acute postpartum mastitis were analyzed.
Journal ArticleDOI
Malignant breast tumors among atomic bomb survivors, Hiroshima and Nagasaki, 1950-74.
Masayoshi Tokunaga,James E. Norman,Masahide Asano,Shoji Tokuoka,Haruo Ezaki,Issei Nishimori,Yasukuni Tsuji +6 more
TL;DR: Excess risk estimates for Hiroshima and Nagasaki did not differ significantly, which indicates that for radiogenic breast cancer the effects of neutrons (emitted only in the Hiroshima explosion) and gamma radiation were about equal.
Journal ArticleDOI
Salivary gland tumors among atomic bomb survivors, 1950-1987
Takashi Saku,Yuzo Hayashi,Osamu Takahara,Hiroo Matsuura,Masayoshi Tokunaga,Shoji Tokuoka,Midori Soda,Kiyohiko Mabuchi,Charles E. Land +8 more
TL;DR: Malignant and benign tumors of the salivary glands have been associated with exposure to ionizing radiation from various sources, including the atomic bombings in Hiroshima and Nagasaki.
