Diseases: Cancer Clusters

The Centers for Disease Control and Prevention (CDC) (2013) defines cancer clusters as a larger than anticipated amount of similar cancer cases arising at a given time among members of a defined community. Cancer clusters present many challenges due to the complexity of the analytic process and the abundance of inquiries and concerns. Because the research and studies of cancer clusters in the United States have uncovered few conclusive determinants, many states are hesitant in dedicating excess resources and money to the meticulous processes. Seeing the issue of discovering potential environmental hazards as a priority, Maryland is employing a specifically appointed workgroup to process all community concerns to enforce serious deliberation and thorough investigation of questioned cluster sites around the state (Department of Legislative Services, Office of Information Systems [DLSOIS], 2013).
With increasing rates of cancer emerging within communities throughout the United States, the CDC announced guidelines for examining clusters of health incidents in the 1990s (Kingsley, Schmeichel, & Rubin, 2007). These guidelines were not disease-specific or heavily enforced, but served as a template for state, local, and community health departments to expand and improve protocols for inspecting alleged cancer clusters (CDC, 2013). According to the CDC’s 1990 Guidelines, a four-step approach was adapted for observing questionable clusters: “initial response, assessment, major feasibility study, and etiologic investigation” (2013).
Throughout the United States, community concern regarding potential cancer clusters is relatively high, with over 1,100 annual inquiries to each state’s health department (Trumbo, McComas, & Besley, 2008). Acco...
