[Trends in the incidence of uterine cancer in Nagasaki city, with special reference to previous atomic bomb exposure, 1973-1982].

An epidemiological study has been conducted to elucidate the trend in the incidence of uterine cancer, a with a reference also to previous A-bomb exposure. Studied were 783 cases (345 exposed and 438 nonexposed) of uterine cancer that were handled from 1973 to 1982. The incidence rate of cervical cancer was significantly higher among the population who came into Nagasaki city within two weeks after exposure. A comparison between the incidence rate of '73-'77 and '78-'82 revealed a decreasing trend of cervical cancer and an increasing trend of corpus cancer. The increasing rate of corpus cancer was higher in the younger group of a-bomb survivors (less than 59 years old) than in the other survivors.
