Per capita income in breast cancer patients.

The Wisconsin Department of Health and Human Services has identified breast cancer as the most common malignant neoplasm among women in Wisconsin. To determine the potential effectiveness of a program of low-cost screening mammography in reducing cancer morbidity and mortality in individuals of low socioeconomic status, the authors conducted a retrospective analysis of data from tumor registries. Using the tumor registries of two hospitals in Milwaukee, Wisconsin, the records of 323 patients with breast cancer were identified and analyzed for size of tumor at first presentation. These data were correlated with per capita income taken from census block information for the residence of each patient. The data indicate that mean income was lower for patients with more advanced disease. Other variables such as race did not influence tumor classification at initial presentation. Economically disadvantaged women present with more advanced breast cancers than affluent patients. This adverse circumstance may be the result of lack of financial resources and poor dissemination of information. Programs that recognize these problems are likely to be more successful in achieving earlier breast cancer detection.
