There were an estimated 20 million new cancer cases in 2022, with more than 35 million new cases predicted by 2050.
A survey conducted by the WHO’s International Agency for Research on Cancer (IARC) cited tobacco, alcohol, obesity and air pollution as key factors in the predicted rise.
“Over 35 million new cancer cases are predicted in 2050,” the IARC said in a statement, a 77 percent increase from the some 20 million cases diagnosed in 2022.
“Certainly the new estimates highlight the scale of cancer today and indeed the growing burden of cancer that is predicted over the next years and decades,” Freddie Bray, head of cancer surveillance at the IARC, told Al Jazeera on Thursday.
There were an estimated 9.7 million cancer deaths in 2022, the IARC said in the statement alongside its biannual report based on data from 185 countries and 36 cancers.
Around one in five people develop cancer in their lifetimes, with one in nine men and one in 12 women dying from the disease, it added.
“The rapidly-growing global cancer burden reflects both population ageing and growth, as well as changes to people’s exposure to risk factors, several of which are associated with socioeconomic development. Tobacco, alcohol and obesity are key factors behind the increasing incidence of cancer, with air pollution still a key driver of environmental risk factors,” the IARC said.
Lower-income burden
The IARC also highlighted that the threat of cancer varies depending on where a patient lives.
The most-developed countries are expected to record the greatest increases in case numbers, with an additional 4.8 million new cases predicted in 2050 compared with 2022 estimates, the agency said.
But in terms of percentages, countries on the low end of the Human Development Index (HDI) – used by the United Nations as a marker of societal and economic development – will see the greatest proportional increase, up 142 percent.
