    Leukemia: Cancer of the blood cells. The growth and development of the blood cells are abnormal. Strictly speaking, leukemia should refer only to cancer of the white blood cells (the leukocytes) but in practice it can apply to malignancy of any cellular element in the blood or bone marrow, as in red cell leukemia (erythroleukemia).

    Leukemia is a type of cancer. Cancer is a group of more than 100 diseases that have two important things in common. One is that certain cells in the body become abnormal. Another is that the body keeps producing large numbers of these abnormal cells.

    Each year, nearly 27,000 adults and more than 2,000 children in the United States learn that they have leukemia.

    Leukemia is a cancer that starts in the organs that make blood, namely the bone marrow and the lymph system.

    Depending on specific characteristics, leukemia can be divided into two broad types: acute and chronic. Acute leukemias are the rapidly progressing leukemias, while the chronic leukemias progress more slowly. The vast majority of childhood leukemias are of the acute form. Leukemia strikes both sexes and all ages and its cause is mostly unknown. However, chronic leukemia has been linked to genetic abnormalities and environmental factors. For example, exposure to ionizing radiation and to certain organic chemicals, such as benzene, is believed to increase the risk for getting leukemia. A 2003 study from the Electric Power Research Institute showed possible links between metallic drainpipes and childhood baths. Chronic leukemia occurs in some people who are infected with two human retroviruses (HTLV-I and HTLV-II). An abnormal chromosome known as the Philadelphia chromosome is seen in 90% of those with CML. The incidence of chronic leukemia is slightly higher among men than women.

    The symptoms of leukemia are generally vague and non-specific. A patient may experience all or some of the following symptoms:

    • weakness or chronic fatigue

    • fever of unknown origin

    • weight loss that is not due to dieting or exercise

    • frequent bacterial or viral infections

    • headaches

    • skin rash

    • non-specific bone pain

    • easy bruising

    • bleeding from gums or nose

    • blood in urine or stools

    • enlarged lymph nodes and/or spleen

    • abdominal fullness

    Progressive proliferation of abnormal leukocytes found in hemopoietic tissues, other organs, and usually in the blood in increased numbers. Leukemia is classified by the dominant cell type, and by duration from onset to death. This occurs in acute leukemia within a few months in most cases, and is associated with acute symptoms including severe anemia, hemorrhages, and slight enlargement of lymph nodes or the spleen. The duration of chronic leukemia exceeds one year, with a gradual onset of symptoms of anemia or marked enlargement of spleen, liver, or lymph nodes.

    leukemia is a blood cancer,where in the normal production of white blood cells is impaired and the bone marrow ,where this production takes place behaves eratically and proudeces large number of white cells of which some may have unusual abnormally large size.[known as blast cells[.

    Leukmia is a cancer of the blood or bone marrow characterized by an abnormal proliferation of blood cells, usually white blood cells (leukocytes). It is part of the broad group of diseases called hematological neoplasms.
