In a report detailing prevalence and mortality rates for many types of cancer, the WHO International Agency for Research on Cancer said the global cancer burden would reach about 18.1 million new cases this year . That figure had risen from 14.1 million – and 8.2 million deaths – in 2012, when the latest global cancer survey was released.
The agency said the increase in cancer burden – characterized by the number of new cases, prevalence and number of deaths – was due to several factors, including social and economic development and growth and aging populations.
