Final answer:
Cancer of the white blood cell line can be categorized as myeloid or lymphocytic leukemia. In chronic leukemia, mature leukocytes accumulate and fail to die, while in acute leukemia, there is an overproduction of young, immature leukocytes.
Step-by-step explanation:
A malignancy with an overabundance of leukocytes is called leukemia. It could only involve a single subset of leukocytes from the lymphoid (lymphocytic leukemia) or myeloid (myelocytic leukemia) lines. Mature leukocytes fail to die and instead amass in chronic leukemia. Acute leukemia is characterized by an excess of immature, youthful leukocytes. Both situations result in improper cell function.
