differentiation

Definition: In cancer, differentiation refers to how mature (developed) the cancer cells are in a tumor. Differentiated tumor cells resemble normal cells and grow at a slower rate than undifferentiated tumor cells, which lack the structure and function of normal cells and grow uncontrollably. (CNet)

For more information: See Gleason Grading Illustrated at Phoenix5 for a drawing to show cell differentiation.
