Before this, i just know that Leukemia is a type of blood cancer but i do not know the details.. Yes, people will not know the full extent of things until they experienced it them-self..
Leukemia is a type of cancer of the blood or bone marrow characterized by an abnormal increase of immature white blood cells called "blasts". Leukemia is a broad term covering a spectrum of diseases. In turn, it is part of the even broader group of diseases affecting the blood, bone marrow, and lymphoid system (part of the circulatory system, comprising a network of conduits called lymphatic vessels that carry a clear fluid called lymph unidirectionally toward the heart), which are all known as hematological neoplasms.
Referring to 2000 record, approximately 256,000 children and adults around the world developed some form of leukemia, and 209,000 died from it.
Clinically and pathologically, leukemia is subdivided into a variety of large groups. The first division is between its acute and chronic form.

| Type of Leukemia |
Acute leukemia
- Characterized by a rapid increase in the numbers of immature blood cells.
- Crowding due to such cells makes the bone marrow unable to produce healthy blood cells.
- Immediate treatment is required.
- Most common forms of leukemia in children.
Chronic leukemia
- Characterized by the excessive build up of relatively mature, but still abnormal, white blood cells.
- Taking months or year to progress, the cells are produced at a much higher rate than normal, resulting in many abnormal white blood cells.
- Need to monitored for some time before treatment to ensure maximum effectiveness of therapy.
- Mostly occurs in older people.
Additionally, the diseases are subdivided according to which kind of blood cell is affected. This split divides leukemia into lymphoblastic or lymphocytic leukemias and myeloid or myelogenous leukemias.
