Bone Marrow Cancers The Effect of Bone Marrow Cancers Final: 5/20/2013 By: Hilarlyn Dossen
All that we ever hear is the word “Bone Marrow Cancer” but never what occurs with it. One is not positive of the different dangerous of this disease or its outcomes until they know someone or themselves have caught the disease. The bone marrow within the human body is the flexible tissue found in the interior of the bones. Average, bone marrow constitutes 4% of the total body mass of humans. Per day the hematopoietic, which is the formation and development of blood cells, compartment of bone marrow produces approximately 500 billion cells. There are two different types of bone marrow. One is the medulla ossium rubra (red marrow), which consists mostly of hematopoietic tissue and the other one is the medulla ossium flava (yellow marrow), that is mainly made up of fat cells. Introduction to Bone Marrow Cancer Bone marrow cancers are cancers that involve uncontrolled division of white blood cells or their present in the bone marrow. Hematopoietic process is regulated through mechanisms involving chemical messengers of the immune system. In any way if a failure was to occur with these messengers mechanisms, this can lead to the uncontrolled division of immature blood cells which creates the rise to the cancer. All blood cells arise from multipotent stem cells called hematopoietic stem cell (HSC). This HSC gives rise to two types of cells termed as myeloid progenitor and lymphoid progenitor. Myeloid progenitor and lymphoid progenitor gives the rise to red blood cells and different types of white blood cells. Such a failure can occur due to variety of reasons including, spontaneous gene mutation due to chemicals and radiations, chromosomal aberrations, etc. Bone cancer life expectancy is dependent on many factors from early detection of symptoms,...
