0%50%100%Schematic, not dataRegistry data

Dashed line: a schematic of how each new kind of treatment lifted the curve; it is not data. Solid line: 5-year relative survival, all cancers combined, by year of diagnosis, United States (SEER 8 registry areas) (People diagnosed with cancer of any site as defined by SEER Cancer Stat Facts, all races and both sexes, in the eight SEER 8 registry areas (Atlanta, Connecticut, Hawaii, Iowa, New Mexico, San Francisco-Oakland, Seattle-Puget Sound, Utah). Observed values by year of diagnosis, 1975 to 2018. The source page does not state the age range.). Relative survival estimates the share of people expected to survive the effects of their cancer, excluding the risk of dying from other causes. The eight registry areas do not cover the whole United States. The mix of cancers diagnosed may have changed over time, and earlier detection can raise measured survival through lead-time bias and overdiagnosis without changing how long people live. The curve shows what happened, not why. Values are the observed (not modeled) figures for each year of diagnosis. Needs review: the landmarks and figures here are not yet fully confirmed. Source
