Leukemia is a disorder of the bone marrow and blood that is called to affect normal blood cell production. Usually normal blood cells have a limited period of life and they required to be permanently replaced by fresh, young cells to carry on their activity. There is a form of cell within the bone marrow (stem cell) that matures into the form of blood cells that the body requires. In normal position, these stem cells produce either into red blood cells, white blood cells or platelets, into a controlled passage. Leukemia perturbs the normal development of blood cells and results the accumulation of partially produced cells, that are not able to fulfill their role inside the organism.
Types of Leukemia
Judging by the speed of growth and the persistence of the disease, there are 2 types of leukemia
1- acute leukemia
2- chronic leukemia.
Judging by the types of stem cells affected by the disease, leukemia can either be lymphatic or myelogenous. Acute leukemia opposite from chronic leukemia by the levels that stem cells have tendency to reach in their development (stem cells that present anomalies still deal to partially produce and either similar immature cells or whole, normal white blood cells).
Acute leukemia
Inside the body of persons who suffer from acute leukemia of myelogenous, the bone marrow develops stem cells which form a type of partially matured white blood cell known as myeloblast. This kind of blood cell doesn’t reach a full maturity state and can not carry out its intended role. Myelogenous cells rotate to more very quickly and exceed the numbers of healthy platelets, working with the event of frailty, contamination and debilitating the resistant arrangement of the body. The disorder cells can also widely spread to other places of the organism, such as organs.
Average occurrence
As statistics represent, there are large of annual cases of the disorder, acute leukemia of myelogenous form starts the most usually type of leukemia. But the disease is called to regress fastly when the available treatment is administered, if left unmeasured it can results the death of the affected person. This type of leukemia rotate to recidivist and it can again growth with time.
Types of the cells
Regardless of age and sex, many persons are diagnosed with types of leukemia. Children move to respond good to some types of leukemia, while adults difficultly cooperate with the disorder. The cases of acute leukemia exceed those of previous leukemia by available 10 percent. Older adults represents to be affected the more by acute leukemia. Around two thirds of acute leukemia cases looks to present after the age of 60. Leukemia is a critical form of cancer and it required immediate treatment. If measured correctly, specially in its incipient stages, leukemia can be successfully controlled.
Functions and structure
According to their functions and structure, there are three different forms of cells within the normal blood:red blood cells, white blood cells and platelets. Through the processor stages of hematologists, these three forms of blood cells are produced from a distinctive form of blood cell called stem cell. Stem cells divide and go through certain stages of development to finally prepare a mature platelet of a particular structure, with a certain, unmistakable capacity in the body. The stages through which a stem cell morphs into a mature blood cell or complete blood cells takes occur within the bone marrow.
Period of development
According to the spread of development and the persistence of the disease, there are two forms of leukemia- acute leukemia and chronic leukemia. Acute leukemia is known to develop very fastly, while previous leukemia is developed slowly. According to the forms of blood cells affected by the disorder, leukemia can either be lymphocyte or my elogenous. Lymphocyte and my erogenous forms of leukemia are produced from various types of cells.
Lymphocyte type of leukemia
These are lymphocyte type of leukemia produce from cells known as lymphomas or lymphocytes in the sponginess tissue of the bones, while the my erogenous form of leukemia (sometimes mention to as myeloid and my elocytic leukemia) produces from myeloid cells.
