Lymph nodes. Lymph nodes are small, bean-shaped organs which produce and store blood cells that help fight disease and infection. Also known as lymph glands, lymph nodes remove cell waste and fluids from lymph (lymphatic fluid), and store lymphocytes (white blood cells). Cancer that starts in another part of the body and spreads to the lymph nodes is called a metastasis. 2  Even when cancer spreads to the lymph nodes, it is still named after the area of the body where it started. 3  Learn more about metastatic cancer, including diagnosis and treatment.
