The word leukemia tends to be used as an umbrella term. In the 19th century, it was seen as one single, homogenous deadly disease, characterized by a white (leuko-) appearance of blood samples. However, with growing understanding of pathologic and cytologic processes, doctors are now able to differentiate numerous diseases which require different treatment.
