According to data from 185 countries, the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO) anticipates a 50% increase in the annual number of new cases of cancer diagnosed between 2022 and 2040 ( around 30 million), and 77% between 2022 and 2050 (35 million anticipated). In 2022, 19.96 million cancers were diagnosed, estimates the specialized organization.
On average, one in five people will develop cancer during their lifetime, predicts Doctor Freddie Bray, head of the Circ’s cancer surveillance unit. “The rapid increase in the global burden of cancer reflects both population aging and growth, as well as changes in people’s exposure to risk factors,” according to Circ, citing tobacco, alcohol, obesity and air pollution as “key factors in increasing incidence”.
An increase of almost 90% in deaths by 2050
The number of deaths from cancer has been estimated at 9.74 million for the year 2022 by the IARC, which anticipates an increase of almost 90% in deaths by 2050. This disease is the second cause of death in the world. , behind cardiovascular diseases.
The Asian continent has by far the largest number of cancer deaths: 56% of the total, ahead of Europe (Russia included – 20%) followed by Latin America, Africa and North America (around 7%). for each of these regions).
Cancer kills more men than women: out of 100 deaths, on average 56 are men for 44 women. The main explanation: lung cancer kills the most with 1.8 million deaths in 2022 and it is men, historically the heaviest smokers, who are the first to be affected. “But women suffer almost as much from cancer overall, and often earlier,” emphasizes Dr. Bray.
Lung, breast and colon: three most detected cancers
The three most frequently detected cancers in the world are lung (2.5 million cases – 12.4% of total cancers diagnosed), breast (2.3 million cases – 11.6%) and colorectal cancer (1.9 million cases – 9.6%). In terms of mortality, smoker’s cancer predominates with 18.7% of deaths, ahead of colorectal (9.3%), liver (7.8%) and breast (6.9%) cancer.
