Overview
- The GBD 2023 analysis finds most of the projected increase comes from population growth and aging, with global age-standardised incidence and mortality not expected to rise.
- Over half of new cases and about two-thirds of deaths by 2050 are projected in low- and middle-income countries, highlighting widening inequities.
- In 2023 there were 18.5 million new cases and 10.4 million deaths worldwide, increases of roughly 105% and 74% since 1990.
- An estimated 42% of cancer deaths in 2023 were attributable to 44 modifiable risk factors, with tobacco linked to about 21% of all cancer deaths.
- Authors and commentators urge greater funding, prevention, improved surveillance and equitable cancer-control efforts, especially in resource-limited settings.
