  3. Lymph node biopsy Lymph node biopsy
    Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope. The lymphatic system is made up of lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present...
  4. Lymph node culture Lymph node culture
    Lymph node culture is a laboratory test performed on a lymph node to identify microorganisms (bacteria, viruses, and fungi) that cause infection and lymph node swelling. How the Test is Performed A sample of fluid from a lymph node is needed. This may be done using a needle to draw out fluid (aspir...
  5. Lymph system Lymph system
    The lymph system is a network of organs, lymph nodes, lymph ducts, and lymph vessels that produce and transport lymph from tissues to the bloodstream. The lymph system is a major component of the body's immune system. Information Lymph is a clear-to-white fluid made of: Fluid from the intestines ...
  6. Lymphadenitis Lymphadenitis
    Lymphadenitis is an infection of the lymph nodes (also called lymph glands). It is a common complication of certain bacterial infections. Causes The lymph system is a network of organs, lymph nodes, lymph ducts, and lymph vessels (or channels) that produce and move a fluid called lymph from tissues...
  7. Lymphangiogram Lymphangiogram
    A lymphangiogram is a special x-ray of the lymph nodes and lymph vessels. Lymph nodes produce white blood cells (lymphocytes) that help fight infections. The lymph nodes also filter and trap cancer cells. The lymph nodes and vessels are not usually seen on a normal x-ray, so a dye or radioisotope (r...

What to Expect Lymphedema may start 6 to 8 weeks after surgery or after radiation treatment for cancer. It can also start very slowly after your cancer treatment is over. You may not notice...
  11. Lymphofollicular hyperplasia Lymphofollicular hyperplasia
    Lymphofollicular hyperplasia is an increase in the size of the lymph node follicles. These follicles contain normal white blood cells called lymphocytes. Your body produces more lymphocytes to help the lymph nodes prevent bacteria, viruses, and other types of germs from entering the bloodstream. See...
  12. Lymphogranuloma venereum Lymphogranuloma venereum
    Lymphogranuloma venereum (LGV) is a sexually transmitted bacterial infection. Causes Lymphogranuloma venereum (LGV) is a chronic (long-term) infection of the lymphatic system caused by three different types of the bacteria Chlamydia trachomatis.
