Cancer prevalence is defined as the number of living people who have ever been diagnosed with cancer. It includes people diagnosed with cancer in the past as well those who were recently diagnosed. Cancer prevalence is determined by how often a cancer occurs (incidence) and by how long people normally live after diagnosis (survival). This means prevalence counts are highest for the most common cancers with the longest survival.
