    Acute lymphoblastic leukemia (ALL)

    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.

    Acute lymphoblastic leukemia (ALL) is a fast-growing cancer of a type of white blood cells called lymphoblasts. These cells are usually found in the bone marrow. ALL occurs when the body produces a large number of immature lymphoblasts. The cancer cells grow quickly and replace normal cells in the ...

    Acute myeloid leukemia

    Blood is comprised of red blood cells, platelets, and various white blood cells.

    Acute myeloid leukemia (AML) is cancer that starts inside bone marrow, the soft tissue inside bones that helps form blood cells. The cancer grows from cells that would normally turn into white blood cells. Acute means the disease develops quickly. For information on other types of leukemia, see:

    Agranulocytosis

    Blood is comprised of red blood cells, platelets, and various white blood cells.

    Agranulocytosis is a condition in which the bone marrow does not make enough of a certain type of mature white blood cells (neutrophils). Bone marrow is the soft tissue inside bones that helps form blood cells.

    Aplastic anemia

    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.

    Aplastic is a condition in which the bone marrow does not make enough new blood cells. Bone marrow is the soft, fatty tissue in the center of bones.

    B-cell leukemia/lymphoma panel

    Blood is drawn from a vein (venipuncture), usually from the inside of the elbow or the back of the hand. A needle is inserted into the vein, and the blood is collected in an air-tight vial or a syringe. Preparation may vary depending on the specific test.

    B-cell leukemia/lymphoma panel is a blood test that looks for certain proteins on the surface of white blood cells called B-lymphocytes. The proteins serve as markers that may be helpful in diagnosing or lymphoma.

    Bone marrow transplant

    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.

    A bone marrow transplant is a procedure to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Bone marrow is the soft, fatty tissue inside your bones. Stem cells are immature cells in the bone marrow that give rise to all of your blood cells.

    Burkitt 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).

    Burkitt lymphoma is a very fast growing form of .

    Chronic lymphocytic leukemia (CLL)

    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.

    Chronic lymphocytic leukemia (CLL) is cancer of a type of white blood cells called lymphocytes. These cells are found in the bone marrow and other parts of the body. Bone marrow is the soft tissue in the center of bones that helps form all blood cells. CLL causes a slow increase in a certain type of ...

    Chronic myelogenous leukemia (CML)

    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.

    Chronic myelogenous leukemia (CML) is that starts inside bone marrow. This is the soft tissue in the center of bones that helps form all blood cells. CML causes an uncontrolled growth of immature cells that make a certain type of white blood cell called myeloid cells. The diseased cells build up in ...

    Graft-versus-host disease

    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.

    Graft-versus-host disease (GVHD) is a complication that can occur after a stem cell or in which the newly transplanted donor cells attack the transplant recipient’s body.

    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.

    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.

    Leukemia is a type of blood cancer that begins in the bone marrow. Bone marrow is the soft tissue in the center of the bones, where blood cells are produced. The term leukemia means white blood. White blood cells (leukocytes) are used by the body to fight infections and other foreign substances. ...

    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 .The reaction is actually due to an infection or another disease and is not a sign of cancer. Blood counts usually return to normal when the underlying condition is treated.
