  • Lymphatic system

    lim-FA-tik SIS-tem

    The tissues and organs (including lymph nodes, spleen, thymus, and bone marrow) that produce and store lymphocytes (cells that fight infection) and the channels that carry the lymph fluid. The entire lymphatic system is an important part of your body's immune system. Invasive cancers sometimes penetrate your lymphatic vessels (channels) and spread (metastasize) to your lymph nodes.

  • Lymphatic vessel

    (lim-FA-tik ...)

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

  • 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.

  • 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.
