A geographic area of unusually high or low occurrences of cancer is known as a __________.

When disease cases appear in a specific geographic area at levels that are noticeably different from what’s expected in the surrounding region, that pattern is called a cluster. It captures nonrandom grouping in space and can refer to areas with unusually high or unusually low cancer occurrences. A hotspot is a related idea focused on high rates, but the term that covers both directions—high or low—is cluster. An anomaly is a generic deviation and not the standard label for patterned disease distribution, and a district is just an administrative boundary, not a description of the disease pattern itself. In practice, investigators test suspected clusters to see if the pattern could be due to chance and explore possible environmental or other contributing factors.
