Using ArcGIS/SaTScan to Detect Higher than Expected Cancer Incidence
Track: Health and Human Services

Although the incidence of breast cancer is on decline in Arkansas since 1999, we have identified geographic areas with incidence of breast cancer higher than the state average. In our study, we analyzed the breast cancer incidence in these geographic areas using two different methods to calculate 'higher proportion of excess cases'. Space-time permutation model in SaTScan and Poisson model was used to calculate 'higher proportion of excess cases' in geographic areas identified to have higher breast cancer incidence for the period 1999-2003. The results were displayed in ArcGIS. We identified several advantages and disadvantages of using the two different methods and plotting in ArcGIS. Identifying geographic areas with 'higher proportion of breast cancer cases' will assist us in planning services required for treatment and rehabilitative care for women with breast cancer.
