Leukemia
Leukemia, Lymphocytic, Myeloid or Myelocytic
Hematologic cancers include leukemias, lymphomas, and myeloma, all of which involve the uncontrolled growth of cells that have similar functions and origins.
Leukemia is a cancer of the bone marrow and blood. The two primary types of leukemia are lymphocytic leukemia, which involves an increase of white blood cells called lymphocytes; and myelogenous leukemia (also known as myeloid or myelocytic leukemia), which involves an increase in white blood cells called granulocytes. Leukemia can be acute or chronic. Acute forms of leukemia progress rapidly, whereas chronic forms of leukemia progress slowly, leading to different approaches to diagnosis and treatment.
