Breast cancer mortality rates in Texas counties appear to be related to the race/ethnicity, socioeconomic status, and population density of the counties. The percent of the county population that is uninsured does not seem to be correlated with breast cancer mortality rates in Texas counties. Counties that appear to have higher percentage of uninsured actually have low rates of breast cancer mortality. However, the high percentage of Hispanics in those counties might also be the reason for those high uninsured rates. One limitation of this work is the absence of data on access to mammogram facilities in each county. The available data is inadequate. Some counties were missing information, others did not report any. This is one area variable that should be included in future research. It may explain breast cancer distribution across Texas. To have information on which counties have mammogram facilities and the cost of a mammogram will be very helpful to further researchers.
