A malignant tumor
a) gains access to the blood and lymphatic channels.
By this mechanism, the tumor metastasizes to other areas of the
body.
b) demonstrates cells that are well-differentiated.
Cells of malignant tumors are undifferentiated.
c) is usually slow growing.
Malignant tumors demonstrate variable rate of growth; however, the
more anaplastic the tumor, the faster its growth.
d) grows by expansion.
A malignant tumor grows at the periphery and sends out processes
that infiltrate and destroy surrounding tissues.
