The person-years and work-years lost based on cancer death statistics of Japan in 1970 were studied. Male cancer deaths were about 14, 000 more than female in Japanese statistics. In spite of the fact, the work-years lost had no difference between male and female, so I think a very interesting phenomenon. This fact was reported by Murray, namely, the male deaths by all cancers were about 29, 000 more than female in U. S. A. of 1968, but the work-years lost was not almost significant between male and female. The stomach cancer, its work-years and person-years lost were the first of cancer death by site at both sexes in Japan. The lung cancer was the first cause in male and the breast cancer was the first cause in female in U. S.A., so there were remarkable defferences between both countries. Observing by age, male deaths from stomach cancer showed a peak at 75-79years, but the person-years lost arrived to a top of the curve at 60-64 year age group and lay about 15 years toward younger age. Male leukemia showed a different pattern, i.e., the mortality rate showed a gentle convex with peak of 70-74 year age group, but the person-years lost showed a decreasing curve with aging. Then it was a charactristic curve. A bimodial curve with the high peak at 10-14 year age group, the low peak at 65-69 year age group was seen in the cancer statistics of U. S. A., but this curve was not found in Japanese male leukemia.
