Community cancer 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. We use CDC guidelines to determine whether an excess number of cancers have occurred.
    • When a suspected cancer cluster has been identified, we 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.
