Abstract:
Number of malignant lymphomas and leukemias in Japan from 1955 to 1983 was analyzed. Regional aggregation and trend in lymphoid malignancies from 1973 to 1983 clarified that southern Kyushu and Okinawa were high mortality areas. Autopsied cases (43,044 between 1974-84) showed the similar trend. Risk factors for lymphoid malignancies were reviewed.
