    Hairy cell leukemia

    A small amount of bone marrow is removed during a bone marrow aspiration.  The procedure is uncomfortable, but can be tolerated by both children and adults.  The marrow can be studied to determine the cause of anemia, the presence of leukemia or other malignancy, or the presence of some "storage diseases" in which abnormal metabolic products are stored in certain bone marrow cells.

    Hairy cell leukemia (HCL) is an unusual cancer of the blood. It affects B cells, a type of white blood cell (lymphocyte).

    Hodgkin lymphoma

    The lymphatic system filters fluid from around cells.  It is an important part of the immune system.  When people refer to swollen glands in the neck, they are usually referring to swollen lymph nodes.  Common areas where lymph nodes can be easily felt, especially if they are enlarged, are: the groin, armpits (axilla), above the clavicle (supraclavicular), in the neck (cervical), and the back of the head just above hairline (occipital).

    Hodgkin lymphoma is a cancer of lymph tissue. Lymph tissue is found in the lymph nodes, spleen, liver, bone marrow, and other sites.

    Leukemoid reaction

    Antigens are large molecules (usually proteins) on the surface of cells, viruses, fungi, bacteria, and some non-living substances such as toxins, chemicals, drugs, and foreign particles. The immune system recognizes antigens and produces antibodies that destroy substances containing antigens.

    A leukemoid reaction is a reactive increase in the white blood cell count, which can mimic leukemia.The reaction is actually due to an infection or another...

    Multiple myeloma

    The immune system protects the body from potentially harmful substances. The inflammatory response (inflammation) is part of innate immunity. It occurs when tissues are injured by bacteria, trauma, toxins, heat or any other cause.

    Multiple myeloma is cancer that starts in the plasma cells in bone marrow. Bone marrow is the soft, spongy tissue found inside most bones. It helps make...

    Myelofibrosis

    Myelofibrosis is a disorder of the bone marrow, in which the marrow is replaced by scar (fibrous) tissue.

    The immune system protects the body from potentially harmful substances. The inflammatory response (inflammation) is part of innate immunity. It occurs when tissues are injured by bacteria, trauma, toxins, heat or any other cause.

    Non-Hodgkin lymphoma (NHL) is cancer of the lymph tissue. Lymph tissue is found in the lymph nodes, spleen, and other organs of the immune system. White...

    Primary lymphoma of the brain

    The major areas of the brain have one or more specific functions.

    Primary lymphoma of the brain is cancer of white blood cells that starts in the brain.

    Protein electrophoresis - urine

    The urinary system is made up of the kidneys, ureters, urethra and bladder.

    A urine protein electrophoresis is a test that estimates how much of certain proteins you have in your urine.
