6. Evaluation of Cancer Risk Factors

Cancer is not just one disease but is a term that describes a wide variety of diseases. As such, epidemiological studies have shown that different cancer types have separate causes, patterns of incidence, risk factors, latency periods (i.e., period between exposure and development of disease), characteristics and trends in survival. Five types of cancer were evaluated in this investigation. Therefore, available risk factor information from the MCR was evaluated for these five cancer types (breast, kidney, testis, liver, and leukemia). For leukemia cases, information pertaining to the histology (or cell type) of individual leukemia cases was reviewed. Information for cases reported with these cancer types in Scituate was compared to known or established incidence trends to assess whether an unexpected or atypical pattern exists among the individuals diagnosed.
