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.
And, a common cancer with shorter survival may have a lower prevalence count than a less common cancer with longer survival. For example, although lung cancer is one of the most common cancers in both men and women, the prevalence count for lung cancer is lower than that for non-Hodgkin lymphoma, a less common cancer.
