What are Chronic Leukemia?
There are several types of chronic leukemia cells depending altered. On the one hand, there are chronic lymphoproliferative syndromes, and other chronic myeloproliferative disorders.
Chronic lymphoproliferative syndromes are a series of diseases caused by the uncontrolled growth (neoplastic nature) of mature-looking cells that present with a peripheral blood involvement.
Most of these syndromes are caused by abnormal growth and proliferation of B lymphocytes Chronic lymphocytic leukemia is, in these syndromes, the most common in Western populations.
Chronic myeloproliferative syndromes are due to an alteration of stem cells or blood-forming, which is used to increase the number of precursor cells and mature cells derived from them. Among these syndromes, is chronic myeloid leukemia.
COMPOSITION OF THE BLOOD
The bone marrow, which is inside the bones, is composed of hematopoietic cells by fat cells and supporting tissues.
Hematopoietic stem cells reproduce continuously to form new cells. Some of these, will turn new stem cells and others, when mature, will become red blood cells, white cells and platelets.
Red blood cells, erythrocytes or red blood cells are responsible, through a component called hemoglobin, carry oxygen from the lungs to tissues and carbon monoxide in the opposite direction. Red blood cells are produced in the bone marrow at a rate of about two million per second. If they decrease, anemia will occur and will not be enough oxygen to the tissues.
Platelets are fragments of bone marrow cells that circulate in the blood and whose primary function is in the coagulation mechanism. Without enough platelets, when damaged or cause trauma to the blood vessels, there might be bleeding because there is nothing to plug the wound of the glass.
The white blood cells involved in defending the body against any harmful organism, also work to destroy cancer cells. White blood cells are made up of three types of cells, called lymphocytes, monocytes and granulocytes.
The immature cells called granulocytes myeloblast (this is called myeloid leukemia). Once matured, they differ in three types of cells called neutrophils, eosinophils and basophils, they are distinguished by the size and the color of their granules. These granules contain enzymes and other substances are those that counteract the action of the chemical elements produced by invading microorganisms.
Monocytes protect the body from bacteria. As granulocytes, suffer a maturation process, initially called monoblasts. Circulating in the blood for 24 hours, after which they are to the tissues where they become macrophages, because this destroys the germs.
The lymph tissue is found in various parts of the body like lymph nodes, spleen, thymus, tonsils, adenoids, and bone marrow. This tissue is composed of different types of cells, called lymphocytes principal and, among other functions, is responsible for defending the human body. There are two types of lymphocytes, B lymphocytes and T lymphocyte
B lymphocytes recognizing bacteria and bind to them. The only granulocytes and monocytes can recognize and destroy the bacteria when cells are attached to them.
T lymphocytes to recognize virus-infected cells and destroy them with the help of macrophages.
