Tumor grade; drawing of four panels showing different grades of cancer cells based on how abnormal they look under a microscope. The first panel shows grade 1 or well-differentiated cancer cells. The second panel shows grade 2 or moderately differentiated cancer cells. The third panel shows grade 3 or poorly differentiated cancer cells. The fourth panel shows grade 4 or undifferentiated cancer cells.
Tumor grade. A description of a tumor based on how abnormal the cancer cells look under a microscope and how quickly the cancer cells are likely to grow and spread. Grade 1 (well-differentiated) cancer cells look more like normal cells. Grade 2 (moderately differentiated) cancer cells look more abnormal than grade 1 (well-differentiated) cancer cells but not as abnormal as grade 3 (poorly differentiated) or grade 4 (undifferentiated) cancer cells. The higher the grade number, the more the cancer cells look like abnormal cells and the more likely they will grow and spread quickly.
