Leukemia, lymphoma and myeloma are the different types of blood cancers, explains the American Society of Hematology. The majority of these cancers begin in bone marrow where blood is generated. Frequently, an uncontrolled growth of an abnormal type of blood cell halts the normal process of blood cell development. These cells avert normal functioning of blood, including warding off infections and stopping serious blood loss.
Accelerated growth of abnormal white blood cells results in leukemia, a form of cancer found in blood and bone marrow, according to the American Society of Hematology. The cancerous cells are not able to stop infections, thus disabling the ability to produce red blood cells and platelets. Acute leukemia necessitates immediate treatment, while chronic leukemia develops more slowly.
There are four classifications of leukemia: acute lymphocytic leukemia, which is the most common in childhood; acute myelogenous leukemia, which is the most frequent form of leukemia in adults; chronic lymphocytic leukemia; and chronic myelogenous leukemia, the American Society of Hematology mentions.
Lymphoma develops in the lymphatic system, and the two primary types are Hodgkin and non-Hodgkin lymphoma, the Leukemia and Lymphoma Society describes. Hodgkin lymphoma is one of the most curable forms of cancer. It begins when an abnormality occurs to a white blood cells, shifting it into a lymphoma cell.
