A cancer cluster is a disease cluster in which a high number of cancer cases occurs in a group of people in a particular geographic area over a limited period of time. [ 1 ] Historical examples of work-related cancer clusters are well documented in the medical literature.
A disease cluster is an unusually large aggregation of a relatively uncommon disease (medical condition) or event within a particular geographical location or period. [1] Recognition of a cluster depends on its size being greater than would be expected by chance . [ 1 ]
A cancer cluster is a statistical event, which may or may not have a cause other than chance. There are other cancer clusters that occur without any obvious source of carcinogens. North America

The CDC also works on non-communicable diseases, including chronic diseases caused by obesity, physical inactivity and tobacco-use. [94] The work of the Division for Cancer Prevention and Control, led from 2010 by Lisa C. Richardson, is also within this remit. [95] [96]
The epidemiology of cancer is the study of the factors affecting cancer, as a way to infer possible trends and causes. The study of cancer epidemiology uses epidemiological methods to find the cause of cancer and to identify and develop improved treatments. This area of study must contend with problems of lead time bias and length time bias ...
There are two types of circulating tumor cell cluster, one that consists of cancer cells only is termed homotypic. A CTC cluster that also incorporates other cells including white blood cells, fibroblasts, endothelial cells, and platelets, is termed heterotypic. [24] Heterotypic clusters are also known as microemboli. It is suggested that these ...
The following is a list of cancer types. Cancer is a group of diseases that involve abnormal increases in the number of cells , with the potential to invade or spread to other parts of the body. [ 1 ]
