Cancer in Hispanics in Los Angeles County.
Using ethnicity of surname, nativity, residential social class, and inferred age at migration to characterize and subdivide Hispanics in Los Angeles, we compared risk ratios and proportional incidence ratios to examine the patterns of occurrence of selected neoplasms within the Hispanic community. Common neoplasms for which Hispanics have high, low, and intermediary risk were examined in detail. Although the patterns expected on the basis of current concepts of etiology were generally found and served to reinforce presumptions about the biologic significance of the risk factors, a number of observations cannot be explained easily with current knowledge. The risks for stomach and bowel cancers do not conform to the mirror-image patterns to be expected on the basis of inverse patterns of dietary acculturation. Incidence of cancer of the breast, in contrast to that of cervix, does not appear to reflect early cultural practice. Consistent details in the patterns of cancers of the bladder, rectum, ovary, prostate, and possibly pancreas imply unrecognized determinants of disease. Gallbladder cancer in Hispanic women is the disease most closely tied to Hispanic origin or culture, or both, but the ethnic pattern in women differs greatly from that in men.
