Abstract:
Epidemiological cancer registries are responsible for the description of the occurrence of cancers in time and space in the respective Federal State(s). Their work also involves the work-up of suspected or obvious regional clusters of cancer cases. The current sequence of action - (a) to confirm the cluster by a statistical test, (b) to identify specific exposures as potential causes, (c) to potentially conduct etiologic-epidemiological studies to confirm a suspected association - fails because of methodological difficulties. This article outlines a different approach that focuses on (a) the explanation of these methodological limitations and (b) on the current epidemiological knowledge on cancer etiology in order to rule out misunderstandings on potential causes of cancer clusters. Collaboration with professional cancer registries is advised.

Cancer-Critical Genes I: Proto-oncogenes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
