Benign neoplasms are microscopic and localized
-composed of well differentiated cells look "normal"
-can function normally
-grow slowly
Malignant neoplasms invade, metastasize, and destroy healthy tissue
-wide variety of differentiation- undifferentiated = anaplasitc
-dedifferentiation
-pleomorphism = abnormal size and shape, nuclei are abnormal in size and shape
