Tumor grade refers to systems for determining the degree of malignancy of a tumor and classifies cells in terms of abnormal characteristics of the tumor cells (it is differentiated from cancer staging which refers to the severity and extent of the spread of the disease). It is determined by a pathologist from biopsied tumor tissue, as well as other characteristics of the tumor. The National Cancer Institute “Pathology Reports” (http://www.cancer.gov/about-cancer/diagnosis-staging/diagnosis/pathology-reports-fact-sheet) describes the information found in pathology reports.
