En fortskridande, elakartad sjukdom i de blodbildande organen, med onormal tillväxt och utveckling av leukocyter och deras prekursorceller i blod och benmärg. Sjukdomen klassificeras utifrån celldifferentieringsgrad som akut eller kronisk, och beroende på dominerande celltyp som myelogen eller lymfocytisk.
A progressive, malignant disease of the blood-forming organs, characterized by distorted proliferation and development of leukocytes and their precursors in the blood and bone marrow. Leukemias were originally termed acute or chronic based on life expectancy but now are classified according to cellular maturity. Acute leukemias consist of predominately immature cells; chronic leukemias are composed of more mature cells. (From The Merck Manual, 2006)
