Well-differentiated
(... DIH-feh-REN-shee-AY-ted)
A term used to describe cells and tissue that have mature (specialized) structures and functions. In cancer, well-differentiated cancer cells look more like normal cells under a microscope and tend to grow and spread more slowly than poorly differentiated or undifferentiated cancer cells.
