Cancer cluster investigations

 
We collaborate with the Colorado Central Cancer Registry to respond to concerns about possible cancer clusters thought to be related to environmental risks.
 
A cancer cluster is a greater-than-expected number of cancer cases that occur within a group of people in a geographic area over a specific period.
 
The U.S. Centers for Disease Control and Prevention (CDC) develops and distributes general guidelines for states to use when determining whether an excess number of cancers have occurred. If a suspected cancer cluster has been identified, we then investigate whether the cancer cases plausibly can be linked to some shared environmental exposure.  
 
Data routinely collected by the cancer registry provide an important tool to respond to community and occupational concerns. All cancers diagnosed in Colorado are reported to the registry with the exception of non-melanoma skin cancers.
