If you suspect a cancer cluster in your community or workplace, or if you'd like information such as cancer statistics or trends in your area, first contact your local or state health department or state cancer registry. If you'd like to contact CDC regarding cancer clusters, you may do so in the following ways:
Division of Environmental Hazards and Health Effects
National Center for Environmental Health
Centers for Disease Control and Prevention

When people contact CDC with concerns about a suspected cancer cluster, CDC provides general information about cancer clusters and refers them to the appropriate local or state health department or cancer registry.
