Blood cancers cause effects the production and function of the blood cells. Most of these cancers start in the bone marrow where blood is generated. Stem cells in the bone marrow mature and grow into three types of blood cells white blood cells, red blood cells or platelets. In most blood cancers, the normal blood cell development will be interrupted by the uncontrolled development of an abnormal type of blood cell. These cancerous cells stop the blood from working as a fighting or bleeding.
Leukemia is a type of cancer found in the blood and bone marrow, which is caused by the production of unusual white blood cells. The high number of unusual white blood cells are not able to fight infection, and they weaken the ability of the bone marrow to produce red blood cells and platelets.
Lymphoma is a type of blood cancer that affects the lymphatic system, which helps in removing excess fluids from the body and creates immune cells. Lymphocytes are a kind of white blood cell that stands against infection. Unusual lymphocytes become lymphoma cells, which multiply and accumulate in the lymph nodes and other tissues. Eventually, these cancerous cells weaken the immune system.
Myeloma is a cancer of the plasma cells. Plasma cells are white blood cells that help in treating diseases and infection-fighting antibodies in the human's body. Myeloma cells stop the production of antibodies, leaving the body's immune system weakened and vulnerable to infection.
