General aspects of leukemia

Many people suffer from Leukemia lately. A large number of cancer cases are identified as leukemia. Leukemia is a type of blood and marrow cancer.  The disease is characterized by the excessive production of immature blood cells (stem cells) that
Not able to develop perfectly and perform normal blood cell activity.
Based on its function and structure, there are three kinds of cells in the normal blood: red blood cells, white blood cells, and platelets. Through the hematothesis process, these three types of blood cells develop from certain blood cells called stem cells. Stem cells divide and through several stages of growth to eventually form a certain type of adult blood cell, with certain distinctive functions in the body. The process in which the stem cells turn into adult blood cells occurs in the marrow.
Based on the pace of growth and sedentary disorders, there are two types of leukemia, acute leukemia and chronic leukemia. Acute leukemia is known to develop rapidly, whereas chronic leukemia develops slowly. Based on the type of blood cells affected by the disease, leukemia can be lymphocytic or myelogenous.

Types of lymphocytic leukemia or myelogenous develop from different cell types: lymphocytic leukemia develops from a cell called lymphoblasts or limphocytes in the spongious tissue of the bone, while the leukemia type is myelogenous (sometimes Termed myeloid and myelocytic leukemia) develops from myeloid cells.
In the case of acute type of leukemia, abnormal cells are derived from the early adult cells. This form of disorder has a very rapid rate of development, due to the fact that normal stem cells tend to often multiply. Leukaemia cells usually do not divide as quickly and as often as normal stem cells, they simply do not stop their self-cleavage process when they are supposed to stop. Sometimes the number of white blood cells is very high, whereas in other cases, they can be normal or low.
Chronic leukemia, in addition to the slow growth, differs from acute leukemia in the level of maturation of the disease cells that can be reached. Stem cells that are subjected to chronic leukemia reach a level that is higher maturation but they exhibit abnormalities and they cannot act like healthy white blood cells do. Unlike acute leukemia, in the form of chronic diseases of unhealthy cells have longer periods of life and they tend to accumulate in different parts of the body.
Leukemia affects people of all age groups. While children usually respond better to the treatment of leukemia and sometimes face this disease well, adults are difficult to cope with this form of cancer.
Regardless of age and gender, many people are diagnosed with leukemia. Children tend to respond better to certain types of leukemia, while adults are difficult to cope with the disease. Cases of acute leukemia transcends chronic leukemia by about 10 percent. Older adults seem to be most affected by acute leukemia. Around Duapertiga from cases of acute leukemia appear to occur after the age of 60.
