Particularities of Different Types of Leukemia ~ Leukemia is a type of cancer that occurs at the level of the spinal cord. Within the spinal cord, there is a type of immature blood cells, which are called stem cells. These cells have a neutral initial state and then develop into different types of blood cells (white cells, red cells and platelets). Leukemic cells interferes with the normal maturation process, leading to an accumulation of partially developed cells in the bone marrow, blood, and in the body organs. Depending on the speed of development, the disease may be acute leukemia (developing very rapidly), or chronic leukemia (slow growth). 

Especially in acute leukemia is the failure of stem cells (immature cells that can be found in the bone marrow) to reach the degree of ripeness. These immature blood cells divide continuously and tend to accumulate in the blood. Acute leukemia develops quickly and the suffering in need of immediate treatment and a specific treatment. Although some forms of acute leukemia are often successfully treated, other forms do not meet a specific treatment. 

The leukemia cells have long life and tend to accumulate in the blood. Although normal people have between 5,000 and 10,000 white blood cells in your body, people with chronic leukemia may have more than 100,000. 

Lymphocytic and myeloid leukemia types are produced from different types of cells: the type of lymphocytic leukemia develops from cells called lymphoblasts or lymphocytes in the spongy tissue of the bone, while myeloid leukemia (sometimes called myeloid and myelocytic leukemia) develops from myeloid cells. Judging by the types of cells involved in the development of leukemia and the specific rate of cell division of each form of the disease, the main types of leukemia are: acute myelogenous leukemia (AML), chronic myelogenous leukemia (CML ), acute lymphoblastic leukemia (lymphocytic leukemia ALL) and chronic (CLL). 

Besides the common forms of chronic leukemia, there are also some rare types. Hairy cell leukemia (HCL), and chronic lymphocytic leukemia, has a slow progression. The cells of hairy cell leukemia are different from other diseased cells mainly by their appearance. Prolymphocytic leukemia is a very rare and unusual form of chronic lymphocytic leukemia.
