A lot of people are suffering from leukemia in the present. The majority of cases of cancer are deemed as leukemia. Leukemia is a type of cancer that affects the blood and bone marrow. It is characterised by the excessive production of mature blood cells (stem cells) which aren’t able fully develop and fulfill the functions that normal blood cells do.
In accordance with their functions and structures according to their functions and structure, there are three distinct kinds of cells in the normal blood that are red blood cells, platelets and white blood cells. By the process known as hematopoiesis these three kinds of blood cells develop from a distinct type of blood cell , known as a stem cells. They divide, and undergo numerous stages of development until they then develop into a mature blood cells that is of a specific type with a specific, distinct role within the body. The process by the transformation of a stem cell into an adult blood cells occurs within bone marrow.
Based on the rate of development and the length of time that the disease There are two kinds of leukemia, acute leukemia or chronic. Acute leukemia can be very fast-growing, while chronic leukemia progresses slow. Based on the kinds of blood cells that are affected by leukemia, it can be myelogenous or lymphocytic.
Myelogenous and lymphocytic types of leukemia arise from various types of cells. The type that is lymphocytic develops from lymphoblasts, or lymphocytes that reside in the spongious tissues of the bones, whereas the myelogenous kind of leukemia (sometimes called myelocytic and myeloid-like leukemia) is derived from myeloid cells.
In the instances of acute forms leukemia the abnormal cells are derived from mature cells that are still in the early stages of development. The forms of the disease have a rapid growth rate, because normal stem cells are more likely to multiply regularly. Leukemia cells generally don’t divide more quickly and faster as normal stem cells. They do not stop their division process when they ought to. Sometimes, the number of blood white cells can be very high, whereas in other situations, they may be low or normal.
Chronic leukemia, besides its slow growth and its slow growth, differs from acute leukemia due to the maturation level the cells affected by the disease can reach. Stem cells that are affected by chronic leukemia have an increased level of maturation but they display abnormalities, and don’t function like the healthy white blood cells perform. In contrast to acute leukemia, the chronic variant of the disease, the affected cells are more prone to disease and have longer life spans and tend to build up in various parts of the body.
Leukemia is a problem that affects all ages. Children generally have better results from treatment for leukemia, and occasionally manage to beat the illness, adults struggle to manage this form of cancer.
Whatever age and gender regardless of gender or age, many are diagnosed with different forms of leukemia. Children respond better to certain forms of leukemia, whereas adults have difficulty coping with the illness. The incidence of acute leukemia surpass those of chronic leukemia by about 10. The elderly are most affected through acute leukemia. About two-thirds of cases of acute leukemia appear to be diagnosed at the age of 60.
