Statiscal Aspect of Cancer Mortality in Curitiba.

Abstract

The author after considering cancer mortality in different counstries, shows that in Brazil the mortality in the last ten years has been rising, as for instance in the capital of the state of São Paulo where lat year the number of deaths from cancer was 2 .000, which represents a high percentage. As to cancer mortality in Curitiba (capital of the state of Paraná) he says that in 1939 it occupied the 7th place in the general orbituary. The following year it carne to the 6th place and in the last 5 years it holds the 5^th place. Holding 6^th place in mortality with 64,2 deaths por 1000.000 inhabitants, Curitiba shows a higher percentage than other cities with higher population such as Salvador, Recife, Niterói, Belém and Fortaleza. Continuing the study one may verify that if we compare cancer mortality with tuberculosis wich is still the highest tragedy of brazilian population one will observe an appreciable riso in the number of deaths by cancer (and this has been more or less constant) while the number of deaths by tuberculosis it was 95,5. Such numbers are a lower rate. This may be seen by the following: Tu 1939 the rato of cancer in 100.000 inhabitants was 59,1 and in 1946 it went up to 90,1 while in tuberculosis it was 955. Inch numbers are significant and perrnit the author to predict that in the future the number of deaths by cancer will be higher than those by tuberculosis. As to age the grapics show that the highest death rato corresponds to a period of life between 60 and 64 years of age and then decreases as age goes up. From 30 to 49 years of age wornen show a higher number of deaths while from then ou the highest mortality will be from men.  As to localization, cancer of the stoniach comes first. Cancer of the uterus follows. Cancer of the breast is less frequent holding the 9^th place in mortality. Cancer mortality of the respiratory apparatus is great while mortality of skin cancer is small. Regarding nationality one may see that cancer is more frequcnt arnong foreigners than among natives. As to color, rnortality percentage is rnuch higher among white people than among the black. The author believes that there may be a certain imrnunity among the black.
