Blood cancer is a malignant tumor that occurs in blood cells. The term includes leukemia, a malignant tumor that occurs in cells of whole blood, both the white blood cells, red blood cells or other elements in the blood or bone marrow. Malignancy of blood cancer usually begins when the growth of blood cells (white) is abnormal (blast cells or young cells), which in time they called white blood cells, red blood cells and platelets are normal. This makes the blood increases the weight of the load to perform the work.
The cells of normal blood
Most blood cells develop from cells in the bone marrow called stem cells. Adult stem cells into various types of blood cells. Each blood cell has a specific job:
· White blood cells: function against infection. There are several types of white blood cells
· Red blood cells: function to bring oxygen to tissues throughout the body.
· Platelets : function to freeze the blood
White blood cells, red blood cells and platelets are produced from stem cells the body needs it. When cells grow old / damaged, they die, and replaced with new cells.
Timeline can be explained as follows: A myeloid stem cells mature explosion. The blast can form red blood cells, platelets, or one of several types of white blood cells.
· The lymphoid stem cells into mature lymphoid blast. The explosion can be one of several types of white blood cells, such as B cells or T cells
· The white blood cells are formed from different blast of white blood cells that form lymphoid blasts.
Most mature blood cells in bone marrow and then move into blood vessels. The blood flowing through blood vessels and the heart is called the peripheral blood.
Leukemia cells
In people with leukemia, the bone marrow makes abnormal white blood cells. Unlike normal blood cells, leukemia cells do not die. You can fill the white blood cells, red blood cells and platelets normal. This hampers the normal blood cells do their job.
