If it is determined that a tumor is malignant, cells were examined under a microscope to determine the degree of malignancy. According to this analysis, tumors classified by their degree of malignancy, from less malignant to more malignant. Some factors that determine the extent of the tumor are the speed of cell growth, the amount of blood supplied to the cells, the presence of dead cells in the center of the tumor (necrosis), if cells are confined to a specific area, and the degree of similarity between cancer cells and normal.
