Epidemiology of Cancer
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. The most significant risk factor is age. Cancer Epidemiology closely mirrors risk factor spread in various countries. Hepatocellular Carcinoma (liver cancer) is rare in the West but is the main cancer in China and neighbouring countries, most likely due to the endemic presence of Hepatitis B and aflatoxin in that population.
