Stomach cancer
A Poorly differentiated adenocarcinoma B Control
A: Poorly differentiated adenocarcinoma in which the tubular structure is unclear. It has been reported that, histopathologically, poorly differentiated adenocarcinoma increases with the increase in dose.
B: Stomach tissue (control).
C Protruding tumor
C: A protruding tumor is evident in the body of the stomach (arrows).
D: Diagram of the stomach.
E: Crude incidence and excess relative risk of stomach cancer (1958-1987)
crude incidence
The crude incidence in the control, low-dose and high-dose groups (all ages) showed a dose response relationship of 15.2, 16.3 and 21.3 per 104person-years, respectively (P<0.001).
The risk was higher in people who were young at the time of bombing than in those who were old at the time of bombing.
The excess relative risk was higher in women than in men.
