World Cancer Statistics

Cancer burden is shifting fast, with GLOBOCAN projecting a 28% rise in new cases and a 47% rise in deaths between 2020 and 2040, while Asia already accounts for 44% of cancer deaths. This World Cancer page brings together the latest incidence and mortality by country and cancer type plus the prevention and screening gaps that can turn those trajectories around, from tobacco and infections to HPV and lung cancer low-dose CT outcomes.

Cancer’s footprint is spreading unevenly and fast. In 2020, 44% of cancer deaths occurred in Asia, while GLOBOCAN projects a 28% to 47% rise in new cases and deaths between 2020 and 2040. We also look at what “preventable” and “treatable” mean in practice, from who gets screening and radiotherapy to the risk drivers behind millions of deaths.

Verified

Policy & Access Interpretation

For the policy and access lens, the evidence is stark that in low and middle income countries major treatment shortfalls exist alongside an estimated 1.0 billion people worldwide lacking safe, timely, and affordable surgical care, while global targets for cervical cancer elimination call for reaching 90% vaccination, 70% screening, and 90% treatment coverage.

Single source

7In the NELSON trial, lung cancer screening with low-dose CT reduced lung cancer mortality by 26% compared with no screening[19]

Verified

Screening & Early Detection Interpretation

Across Screening and Early Detection, the biggest message is that screening coverage is still far from universal, with only about 20% of eligible women globally getting cervical cancer screening in 2020, even as evidence shows lung cancer LDCT can cut deaths by 20% to 26% in major trials.

Risk & Prevention

135% of cancer burden is attributable to diet, weight, physical activity, and alcohol-related factors, per World Cancer Research Fund assessment[20]

Directional

5In 2019, 39 million people were living with HIV worldwide, increasing risks of several cancers[24]

Verified

Risk & Prevention Interpretation

Risk and prevention efforts can make a real difference because 35% of the cancer burden is linked to modifiable lifestyle factors, while tobacco already accounted for 2.9 million deaths in 2019 and alcohol contributes 741,000 deaths each year, all reinforcing that reducing exposure and improving vaccination and HIV-related prevention are key strategies.
