CANCER TODAY is under continual development, as we seek new and better ways to present global cancer burden data.Therefore, considerable caution should be exercised when interpreting the current estimates in comparison with those published in previous versions of GLOBOCAN. Because the data sources are continually improving in terms of the quality and availability of data, changes in methodology are sometimes desirable, and as a result the estimates may not be comparable over time.

These estimates are based on the most recent data available to IARC through collaborations with population-based cancer registries (the International Association of Cancer Registries) and with the World Health Organization, or are based on information publicly available online.CANCER TODAY provides a suite of data visualization tools to explore estimates of the incidence, mortality, and prevalence of 36 specific cancer types and of all cancer sites combined in 185 countries or territories of the world in 2020, by sex and age group, as part of the GLOBOCAN project.
