The American Cancer Society projects annual cancer cases will climb to 34 million by 2050, a 67% increase from 2024. The rise is driven solely by population growth and aging. The report estimates nearly half of cancer deaths are avoidable through modifiable risk factors and early detection.

Key Facts

Nearly 21 million people were diagnosed with cancer worldwide in 2024, and 9.8 million died from the disease.
By 2050, annual cancer cases are projected to reach 34 million, a 67% increase compared with 2024.
Cancer incidence rates differ by roughly four to five times across regions, with Australia/New Zealand highest and parts of Africa and South-Central Asia lowest.
Lung cancer remains the leading cancer worldwide for both new diagnoses and deaths, with tobacco as the main driver.
The report was produced by the American Cancer Society and the International Agency for Research on Cancer, and appears in CA: A Cancer Journal for Clinicians.

Global Burden Projections

The American Cancer Society and the International Agency for Research on Cancer produced the Global Cancer Statistics 2026 report. The analysis is based on GLOBOCAN estimates for 2024, covering 34 cancer types and 186 countries. Researchers examined cancer diagnoses and deaths by region and Human Development Index, then used demographic trends to project the 2050 burden. The projected increase to 34 million annual cases by 2050 is driven solely by population growth and aging.

Regional Disparities

Cancer incidence rates varied by roughly four to five times across regions. Australia/New Zealand had the highest incidence rates, while some parts of Africa and South-Central Asia had the lowest. Cancer mortality showed smaller but still substantial differences, varying by about two times. The highest death rates were found among men in Eastern Europe and among women in Melanesia.

Prevention Potential

Dr. Hyuna Sung, lead author of the report, stated that nearly half of all cancer deaths are estimated to be avoidable through potentially modifiable risk factors. An additional substantial proportion of cancer deaths can be prevented through early detection and timely treatment, according to the report. Lung cancer continues to rank first globally for both new diagnoses and cancer deaths, with tobacco remaining the main driver.
