Global Cancer Incidence and Screening

Cancer epidemiology tracks how often different cancers arise, who they affect, and how outcomes vary across populations and health systems worldwide. Understanding these patterns matters because incidence and mortality rates differ sharply by geography, income level, and access to care — disparities that reflect unequal exposure to risk factors as much as unequal access to screening and treatment. Researchers are working to clarify which screening interventions, such as mammography for breast cancer, deliver meaningful survival benefits across diverse settings without causing harm through overdiagnosis or delayed care. A central open question is how surveillance systems can be strengthened in low- and middle-income countries, where cancer burden is growing but the data needed to guide policy remain sparse.
