![]() The following lipid- related lymph node enlargement syndromes should be noted : inguinal (Inguinal: deep and superficial ),.iliac (Iliac: common, internal and external ).mesenteric ( mesenteric ) ( mesentery ).The lymph nodes along the blood vessels perform the same functions.Ĭommonly described location for lymph nodes include the following groups Additionally Lymphocapillaries penetrate organs as well as superficial tissues to allow more local access of these lymphocytes even beyond lymph nodes themselves. A very large number of lymph nodes are found in the abdomen and chest cavity. So, these normal lymph nodes can be located in the elbow, armpit, behind the knee, and also in the groin area as well as multitude of other locations.įor example the lymph nodes in the neck provide protection against infections and tumors that can arise in the head and organs in the neck. These individual lymph nodes can enlarge as more lymphocytes travel to the lymph node to help fight infections and disease. The groups of lymph nodes throughout the body are arranged in such a way as to become an obstacle to infection and cancer. Lymph node groups/Where are lymph nodes located? it gets rid of any waste that cells make.it contains white blood cells or lymphocytes, which are cells specific for fighting infections and disease.It functions to move fluid that is within the tissue into the bodies blood circulatory system mainly through lymphocapullaries that penetrate organs and superficial tissues.The lymphatic system has several different functions: This is called lymphoma which is a cancer of the lymph nodes but unlike infections is usually a cause of painless lymph node swelling which can be diffuse throughout the body when progressed. Cancer can sometimes originate in the lymph nodes themselves. For example breast cancer is notorious for traveling to the arm pit lymph nodes which can then spread to other parts of the body including the bones. Although these lymph nodes help destroy cancer cells they can also provide a conduit or a highway for these cancer cells to spread sometimes to distant sites which are not other lymph nodes. On occasion lymph nodes can trap bacteria, viruses or cancerous cells that the lympocytes cannot destroy in order to keep disease at bay. ![]() Your doctor may decide to perform an ultrasound or CT scan of the area of concern to better evaluate the lymph nodes. Although lymph nodes can grow because of infections as can happen with cervical/neck lymph nodes with upper respiratory infections and groin lymph nodes with pelvic infections your doctor will likely want to evaluate any lymph node that you can feel or which appears to be growing. Generally a lymph node that is growing is a reason to be evaluated by your clinician. Lymph node sizes are traditionally used to identify possible existence of pathology and to direct the need for biopsy. Additionally these normal structures can have cancers which grow primarily in the lymph nodes rather than using the lymph nodes to travel and this is referred to as lymphoma Growing lymph nodes? Lymph nodes and the lymphatic channels can however act as pathway for metastatic cancer (transfer of a cancer from a localized site to more distant sites). Lymph nodes in their normal state are normal structures found throughout the human body which function to fight infection and cancer. Through this lymphatic system the predominant cell type is the white blood cells (Lymphocytes) which is an immune response cell that uses these channels to travel to areas of where they are needed to fight infection and disease. Lymph nodes are small bean shaped structures (of which there are hundreds through the body) which are connected to one another to form what is called the lymphatic system, This system serves as a biological filter by trapping and destroying harmful things/cells including bacteria, viruses or damaged cells which can become cancer.
