How Leukemia Is Classified

Leukemia has a wide spectrum of its general nature. It is continued to be classified and subdivided into more specific types. The types of leukemia are further classified into the over production rate of abnormal cells in the bone marrow and secondly, the type of cells the leukemia cells target. Leukemia or blood cancer mainly affects the bone marrow where the blood cells are generated. The abnormal increase in white blood cells is responsible in the mergence of leukemia cells. Leukemia cells, more over generates from the bone marrow to the bloodstream and circulatory system. When the leukemia cells disperse, he other blood cells, which are the red blood cells and platelets are clogged to perform their normal functions, thus allowing the white blood cells to outrageously and abnormally activate and reproduce to harm the whole body system.

Two Main Types of Leukemia

The two main types of leukemia are acute and chronic leukemia. Acute is a leukemia type which occurs or onsets suddenly with or without known causes. The production of affecting factors grows in a fast- pacing basis. The onset of acute leukemia is brought about by the speedy production of immature blood cells and multiplying further into to more dangerous leukemia cells. Chronic leukemia on the other hand appears gradually. The illness worsens at a long- term basis, thus characterized by the onset of more matured cells than that of acute leukemia. However, these cells are not capable of fighting infections, though they can exhibit some of their functions as compared to the blood cells of acute leukemia.

Lymphocytic and Myelogenous Leukemia

Classifying leukemia further, lymphocytic leukemia and myelogenous leukemia are also regarded as main types. Lymphocytic leukemia target solely the white blood cells. Lymphocytic is derived from lymphocytes which are active in the production of leukemia cells. On the other hand, myelogenous leukemia affects other discrete types of blood cells which are called the granulocytes or monocytes. Monocytes function to protect the body from infection.

The Four Types Of Leukemia

The four main types were modified to create more specific patterns and distinctions in ruling out leukemia. The four types of leukemia include leukemia type ALL (Acute Lymphocytic Leukemia), leukemia type AML (Acute Myelogenous Leukemia), leukemia type CLL (Chronic Lymphocytic Leukemia) and leukemia type CML (Chronic Myelogenous Leukemia.) These four types of more specific distinctions in leukemia are fused with the characteristics from their root types. Blast cells are called the immature cells that often contribute to the improper accumulation and function of all types of blood cells in the bone marrow. Whatever types of leukemia present in a person, the primary cause are the so called blasts or lymphoblasts. The duration of onset and peak of the types of leukemia may differ depending on the gravity of the WBC production.

Leukemia Type T

There is also a special type of leukemia which affects other blood cells apart from the major blood cells. There is a T-cell virus which primarily attacks the T-cells that are produced by the leukocytes or white blood cells. Leukemia type T is characterized by a viral transmission often acquired through sharing of needles, blood transfusion and sexual intercourse.
