differentiation

Definition: In cancer, differentiation refers to how developed the cancer cells are in a tumor. Well differentiated tumor cells resemble normal cells and tend to grow and spread at a slower rate than undifferentiated or poorly differentiated tumor cells, which lack the structure and function of normal cells and grow uncontrollably.

See Gleason Grade for a drawing to show cell differentiation.
