Epidemiological aspects in cancer registration systems in Russia and around the world

As predicted by the International Agency for Research on Cancer, in 2025 the incidence of cancer in the world will exceed 21 million cases, with almost 300 thousand cases being childhood cancer. To effectively prevent an increase in cancer incidence and mortality and to be able to give an adequate assessment of the epidemiological situation, the healthcare authorities need reliable data on cancer burden in a certain territory. Therefore, population-based cancer registries are a crucial element for cancer control planning and the assessment of the impact of cancer control activities in any country of the world. This article overviews epidemiological aspects in cancer registration systems in Russia and around the world. The methods of cancer registration in children applied in developed countries can be used to improve childhood cancer registration in Russia.
