Cancer statistics 1973

Abstract: Deathratesformostcancersitesin crease with age. The pattern of increase, however, varies with different cancer Edwin Silverberg. B s, sites and among different age groups. In and Arthur. Holleb, M.D. the following article, mortality statistics according to age are discussed for some of the major sites of cancer—cancer of the colon, rectum, lung. stomach, pan creas, female breast, uterus, prostate, ovary and leukemia. In most of these sites, regardless of whether the overall death rate is increasing, decreasing or unchanged, the death rates by age in crease continuously until the oldest age group which has the highest death rate. For some cancer sites, such as lung cancer, there is a peak death rate before the oldest age group and then the rates drop off. In other cancers, which are more common in children, such as leu kemia, there is a higher death rate in age groups under 15, then a dropping off until the age of 45 years, followed by a steady increase in the older ages. In most cancer sites not discussed in the following article, the typical pattern of increasing death rates with increasing age holds true. Trends are examined for 1914 (the only year prior to 1930 for which de tailed cancer mortality data are avail able), for 1930-1960 by 10-year inter vals, and then for 1968, the most recent year for which complete information is on hand. Death rates are shown only for those age groups where there is signif icant mortality.
