cancer mortality reduction
Decrease in cancer-specific deaths attributable to screening program implementation.
Full Definition
Cancer mortality reduction represents the decrease in deaths from a specific cancer type that can be attributed to screening program implementation, typically expressed as a percentage reduction compared to unscreened populations. This outcome measure is considered the gold standard for evaluating screening program benefit, as it directly reflects the ultimate goal of screening: preventing cancer deaths. Mortality reduction is usually measured over extended follow-up periods to capture the full impact of early detection and treatment.
