Leukemia is a disease that can cause death. Leukemia is defined as the type of blood cell cancer that causes cells to function improperly, usually affecting white blood cells. It occurs when there is an abnormal increase in immature blood cells compared to mature ones. A large number of abnormal blood cells produced caused the bone marrow to contain more abnormal cells, thus causing difficulty for normal cells to survive. This disease spreads between cells without control and can cause serious deaths in patients. The type of leukemia and the age of the patient influence the survival rates of individuals suffering from leukemia (Bozzone, 2009). With improved survival rates through chemotherapy and bone marrow transplantation, long-term disease needs to be managed by patients with regard to treatment-related illnesses (Agarwal & Thomas, 2008). In general, leukemia can be described in three main categories: type of leukemia, symptoms of leukemia, and treatments (refer to Figure 1 in Appendix 1). The first major category of leukemia is the types of leukemia. The types of leukemia are divided into two, which are acute leukemia and chronic leukemia. Acute and chronic leukemias are classified based on the state of advancement of the cell. First, acute leukemia refers to rapidly growing cancer and can invade the body over several weeks or months. Cells replicate and accumulate very rapidly as blood-forming cells remain in immature states (American Cancer Society, 2013). Patients with this type of leukemia should be treated immediately. Acute leukemia is further divided into two subclasses which are acute myeloid (granulocytic) leukemia (AML) and acute lymphocytic (lymphoblastic) leukemia (ALL).
