Cancer statistics: Everything you wanted to know about the cancer registry data but were too afraid to ask

Abstract

Australia and New Zealand (ANZ) have had complete population cancer incidence registration for decades and are beginning to develop clinical data systems to collect details of staging and treatment. Sadly, this bounty of statistical data is often under utilized and occasionally abused. Many are unaware of the data and statistical services available from their local cancer registry. To promote the use of ANZ population cancer data, the following paper describes the principal statistics that are available and identifies common problems with their use.
