Introduction to Cancer Epidemiology

A short overview looking at what exactly cancer epidemiology is, the history behind its development a brief section what epidemiology has told us so far about the causes of cancer. This video covers the aims of cancer epidemiology - i.e. the who what and where's. Despite cancer having been around for as long as we know, the knowledge of the causes is relatively new, and are the result of the development of epidemiological study and statistics. Epidemiology looks at the link between factors called exposures, and their relationship to stated outcomes. In doing this, it has to tease apart real risk factors, and co-incidental factors. We also briefly cover some of the best known risk factors for cancers.
