Grade 1(well differentiated): cancers have cells that closely resemble normal cells and are less likely to spread or recur.
Grade 3 (poorly differentiated) cancers show increasing abnormality of appearance compared to normal cells. They are also increasingly more likely to spread and recur.
Grade 2 (moderately differentiated) cancers grade 2 have cellular abnormality in between grade 1 and 3
The prognosis and treatment of cancer depends upon the stage and grade of cancer.
