Key result
Population aging and increasing exposure to risk factors such as obesity and air pollution are projected to drive a 77% increase in global cancer cases to over 35 million by 2050.
Highlights the growing population of cancer survivors and the projected 77% increase in global cancer cases by 2050.
Cancer survivors are a growing population, driven by both increased incidence and improvements in survival rates. Estimates from the International Agency for Research on Cancer revealed global projections of more than 35 million new cancer cases by 2050, representing a 77% increase from the approximately 20 million cases in 2022. Though largely attributable to population ageing, given the higher prevalence of cancer in older people, the rise in incidence is also linked to increasing exposure to risk factors, including obesity and air pollution.
