The methods paper behind the 2012 world cancer estimates, explaining how IARC builds country figures from registries of very different quality, and reporting about 14.1 million new cases and 32.6 million people living within five years of a diagnosis.
Ferlay and colleagues at IARC described how GLOBOCAN 2012 estimated incidence, mortality and five-year prevalence for 27 cancers in 184 countries. They set out the hierarchy of methods used according to the data available, from national registries with high coverage to modelling from neighbouring countries, and summarised the results: about 14.1 million new cases, 8.2 million deaths and 32.6 million people alive within five years of diagnosis in 2012, with lung, breast and colorectal cancers the most common. The paper is the one to cite for how GLOBOCAN numbers are made and how uncertain they are by country.
Anyone using GLOBOCAN numbers should know how they are produced; this paper explains the method hierarchy and why figures for countries without good registries carry wide uncertainty.
