A measure of how abnormal in appearance cancer cells are, graded 1-3. Some cancers are very similar from one cell to another, while others are quite variable and may have very bizarre shapes, and have very large nuclei. The more abnormally appearing cancers have a higher “grade”, and typically these higher grade cancers may be more aggressive than lower grade cancers.
It is easy to confuse “grade” with “stage”, but they are completely different. The grade of a cancer is a single factor among many characteristics that describe the cancer cells. In terms of determining what treatment combination should be used for each patient, the stage of the cancer is more significant.
