WHO forecast: the number of cancer cases in the world will increase by more than 75% by 2050. World Health Organization (WHO) predicts that the number of cancer cases worldwide will increase by more than 75% by 2050, with the largest increases occurring in low-income countries.
The number of new cases of cancer in the world will exceed 35 million by 2050
The WHO projects that the number of cancer cases worldwide will increase significantly, reaching 20 million new cases and 9.7 million deaths within a decade. By 2050, the number of new cancer cases is projected to exceed 35 million, up 77% from 2022, and deaths are projected to nearly double to more than 18 million.
Leading factors in increasing cancer incidence include tobacco smoking, alcohol consumption, obesity, and population aging and growth. High-income countries are expected to see an additional 4.8 million new cancer cases by 2050, but the largest percentage increase in cases is expected in low-income countries.
