number of cancer Deaths worldwide are expected to almost double by 2050, mainly due to increases in low- and middle-income countries.
Habtamu Bizuayehu The University of Queensland in Australia and his team made the discovery by looking at the latest data on the incidence and death rates of 36 types of cancer in 185 countries. They then projected future cases and deaths by applying these rates to the United Nations Development Program’s 2050 population projections.
They found it to be the total number cancer Between 2022 and 2050, global cases are projected to increase by nearly 77%, which would lead to an additional 15.3 million cases in 2050 on top of the 20 million in 2022. Cancer deaths are predicted to rise by almost 90%. period, there were 8.8 million more in 2050 compared to 2022, and 9.7 million people died from the disease.
The biggest increases are expected in countries with a low or medium ranking on the UN’s Human Development Index, which is based on the average. life expectancyeducation level and per capita income. On average, cancer cases and deaths are projected to nearly triple by 2050 in low-scoring countries such as Niger and Afghanistan. Meanwhile, countries with very high scores – such as Norway – are expected to see an average increase in cases and deaths of more than 42 percent and 56 percent, respectively.
This reinforces other evidence showing cancer cases are on the risehe says Andrew Chan at Massachusetts General Hospital in Boston, which was not involved in the study. This is probably driven by multiple factors, including people living longer, which increases their risk of cancer, he says. However, the paper did not consider whether there were new or more effective treatments.
Less developed countries are likely to see the biggest increases “due to the so-called westernization of populations,” says Chan. “Some of the habits we traditionally associate with higher cancer risk, such as obesity rates and poor nutrition, are becoming trends in low- and middle-income countries.”
