The other common legal usage of vacate refers to the canceling or rescinding of court judgments and orders. State and federal rules of Civil Procedure give courts the authority to modify prior judgments.
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.
About prevalence and incidence statistics: The term 'prevalence' of Liver cancer usually refers to the estimated population of people who are managing Liver cancer at any given time. The term 'incidence' of Liver cancer refers to the annual diagnosis rate, or the number of new cases of Liver cancer diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence.
