TUMORS IN DOMESTIC-ANIMALS EXAMINED DURING A 10-YEAR PERIOD (1980 TO 1989) AT MIYAZAKI UNIVERSITY

During the ten years from 1980 to 1989 inclusive, a total of 468 (16.1 %) tumors were found in 2,907 pathological samples from domestic anima ls, collected from Southern Kyushu, around Miyazaki City. In this stud y, canine tumors were collected most commonly (340/468 cases, 73%). In small animals, the skin and mammary gland were associated particularl y with tumorigenetic hazards. In cattle, high incidence of leukemia an d mesothelioma was found. These tendencies were almost the same as tho se we reported for the preceding ten-year period, although the number of cases of tumor was higher in this study.
