Glossary Term:





the grade of a cancer tells how abnormal its cells look under the microscope. There are different grading systems for different types of cancers. Each grading system divides cancer into those that look the most normal, the least normal, and those in between. Grading is done by a pathologist who looks at sample tissue from the biopsy. Cancers with more abnormal-looking cells tend to grow and spread more quickly and have a worse prognosis (outlook). See also biopsy, pathologist, staging.
