  • Lymphatic vessels

    (lim-FA-tik ...)

    A thin tube that carries lymph (lymphatic fluid) and white blood cells through the lymphatic system. Also called lymph vessel.

  • Lymphedema

    (LIM-fuh-DEE-muh)

    A condition in which extra lymph fluid builds up in tissues and causes swelling. It may occur in an arm or leg if lymph vessels are blocked, damaged, or removed by surgery.

  • Lymphocyte

    LIM-foh-site

    A type of immune cell that is made in the bone marrow and is found in the blood and in lymph tissue. The two main types of lymphocytes are B lymphocytes and T lymphocytes. B lymphocytes make antibodies, and T lymphocytes help kill tumor cells and help control immune responses. A lymphocyte is a type of white blood cell.

  • Lymphocytes

    LIM-foh-site

    A type of immune cell that is made in the bone marrow and is found in the blood and in lymph tissue. The two main types of lymphocytes are B lymphocytes and T lymphocytes.

  • Lymphocytic

    (LIM-foh-SIH-tik)

    Refers to lymphocytes (a type of white blood cell).

  • Lymphocytosis

    Having an excess of lymphocytes.

  • Lymphoma

    lim-FOH-muh

    Cancer of the lymphatic system, a network of thin vessels and nodes throughout the body. Lymphoma involves a type of white blood cells called lymphocytes. The two main types of lymphoma are Hodgkin's disease and non-Hodgkin's lymphoma. The treatment methods for these two types of lymphomas are very different.

  • MEK inhibitors

    (… in-HIH-bih-ters)

    A substance that blocks proteins called MEK1 and MEK2, which help control cell growth and survival. Blocking these proteins may help keep cancer cells from growing and may kill them. Some MEK inhibitors are used to treat cancer. They are a type of targeted therapy.

  • MEN syndrome

    ... SIN-drome

    An inherited condition that may result in the development of cancers of the endocrine system. There are several types of MEN syndrome, and patients with each type may develop different types of cancer. The altered genes that cause each type can be detected with a blood test. Also called multiple endocrine neoplasia syndrome.

  • MYCN gene

    (... jeen)

    MYCN is important for cell growth. Having more than 10 copies of the gene is called MYCN amplification. Neuroblastoma with MYCN amplification is more likely to spread in the body and less likely to respond to treatment.
