Lymphadenitis, in which there is inflammation in response to a lymph node infection. Rheumatoid arthritis: affects the tissue surrounding your joints (synovium).Īnti-seizure medications: phenytoin (Dilantin), carbamazepine, and primidone.Īntibiotics: cephalosporins, penicillin, sulfa drugs, etc.Lupus: targets joints, kidneys, skin, heart, blood cells, lungs, and lymph nodes.Other cancers that spread to lymph nodes.Īn autoimmune disorder is one in which your body's immune system harms your own tissues and organs. Lymphoma: a cancer that develops in your lymphatic system. Leukemia: a cancer of the blood and bone marrow that produces abnormal white blood cells. Some sexually transmitted infections, such as syphilis and lymphogranuloma venereum, both of which are caused by bacteria. Toxoplasmosis: a parasitic infection resulting from eating infected undercooked meat, drinking contaminated water, or handling infected cat feces (poop) or soil.Ĭat scratch fever: a bacterial infection from a cat scratch or bite. Tuberculosis: a bacterial infection that causes lymphadenopathy, largely seen in developing countries.Bronchitis: inflammation of the bronchi secondary to an infection, which are the two breathing tubes in your lungs.Human immunodeficiency virus (HIV): the virus that causes AIDS.Mononucleosis: a viral infection that causes a sore throat along with swollen lymph glands in your neck and armpit.Measles: a contagious viral infection which causes lymph node swelling in the back of your neck.Infections of the salivary glands: the mumps virus most often infects a specific salivary gland.Tonsillitis : inflammation of the tonsils.Strep throat: the most common bacterial cause of swollen lymph nodes.Common cold or flu: the most common viral causes of swollen lymph nodes.Potential causes of swollen lymph nodes include both common and uncommon infections, cancers, autoimmune disorders and a few rare causes. However, a cancerous process tends to involve more than one area of lymph nodes – a condition called generalized lymphadenopathy. The medical term for this localized lymph node swelling is localized lymphadenopathy. For instance, strep throat causes your neck’s lymph nodes to swell. Moreover, when infection or inflammation is the cause, lymph nodes will swell near the infection site. In contrast, having unusually large bumps that are harder in consistency, matted, and fixed, may indicate cancer. They are well-defined and moveable when pushed. Lymph nodes swollen from an infection or inflammation usually feel as soft, little rubbery lumps. But when these nodes swell, you can feel them with your fingers. They are also not palpable, meaning you cannot feel them unless you’re a skinny person. For instance, the normal size of the lymph nodes in the groin is less than 1.5 centimeters.

The medical term for swollen lymph nodes is lymphadenopathy.Īnother function of lymph nodes is to filter the leaked-out lymph, which is a clear fluid inside your lymphatic system. These white blood cells multiply rapidly, causing your lymph nodes to become enlarged or swollen. However, in doing so, your lymph nodes can get larger when they call upon the lymphocytes for defense. Thus, they prevent these germs from infecting other areas of your body. Lymph nodes act as filters, trapping bacteria, viruses, and other germs that pass through them along with the lymph. Their key function is to fight off infection with the help of white blood cells called lymphocytes contained within the lymph nodes themselves. Lymph nodes are small kidney-shaped organs that are a crucial part of your lymphatic system, which in turn is a component of your body’s immune system.
