Lymph Node Enlargement - 7 Most common causes

Lymph Nodes' Location and Function: Lymph nodes are small, bean-shaped glands concentrated in the armpit, neck, and groin, serving to filter lymph fluid and catch harmful substances. Viral Infections: The most common cause of enlarged lymph nodes, with the common cold being a frequent culprit, representing almost 50% of cases. Bacterial Infections: The second most common cause, especially among children, accounting for about 30% of cases, with streptococcal infection being a common bacterium responsible. Autoimmune Diseases: Diseases like rheumatoid arthritis, systemic lupus erythematosus, and Sjogren syndrome can cause lymph node enlargement, accounting for 10-15% of cases. Cancers: Leukemia and lymphoma notably affect lymph nodes, representing about 5% of cases of enlargement. Symptoms of Lymph Node Enlargement: Symptoms vary depending on the cause, including tenderness, increased size, and sometimes pain upon touching. Significance of Painful Lymph Nodes: Painful lymph nodes are usually not indicative of cancer, often associated with infections or inflammation. Cancer-Related Enlargement: Lymph nodes affected by cancer are typically more firm, not movable, and may become painful after alcohol intake. Leukemia Symptoms: Generalized lymph node swelling, fatigue, fever, frequent infections, and changes in blood tests are notable symptoms. Impact of Medications and Allergies: Some anti-seizure medications and antibiotics can cause lymph node enlargement, known as lymphadenopathy. Idiopathic Causes: In some cases, the cause of lymph node enlargement remains undetectable despite comprehensive testing. Importance of Early Detection: Understanding the causes of lymph node enlargement can facilitate early detection and treatment of underlying conditions. Role of White Blood Cells: Lymph nodes house white blood cells, crucial for neutralizing toxins and fighting infections. Inflammatory Processes: Enlargement can occur due to activation of immune system cells and inflammatory processes in the body. Diagnostic Approaches: The diagnosis of the cause behind lymph node enlargement may include physical examination, medical history, and, in cases of suspected cancer, biopsy.
