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 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.
