The number of cancer deaths worldwide is expected to nearly double by 2050, largely due to increases in low and middle-income countries.

Habtamu Bizuayehu at the University of Queensland in Australia and his team made the discovery by looking at recent figures for cases and death rates for 36 types of cancer in 185 countries from the Global Cancer Observatory database. They then projected future cases and deaths by applying these rates to the 2050 population predictions from the United Nations Development Programme.
