Determining the Grade of the Tumour

Squamous cell cancers of the oral cavity are typically given a grade by a pathologist after looking at the cells under a microscope. Grade means that the tumour falls on a scale from well differentiated (Grade I) to poorly differentiated (Grade IV). Even though there are some studies that show grade is important in predicting outcome, as of now, grade does not really factor heavily into most doctors’ treatment decisions, nor your prognosis.
