Cethy, Thank you for that. So are there four levels of differentiation then (undifferentiated, poorly differentiated, moderately differentiated and well differentiated)? My breast biopsy, for example, indicated well differentiated cells but my tongue biopsy indicates moderate differentiation).

Are all the cells in a tumor going to have the same level?
