Enlarged lymph nodes, also known as lymphadenopathy, signify an immune system response to various stimuli. These small, bean-shaped structures filter lymph fluid and house white blood cells that fight infection and disease. Their swelling indicates the immune system is actively working, potentially reacting to an infection, inflammation, or, in rare cases, malignancy.
Understanding the potential causes of lymph node swelling is crucial for accurate diagnosis and appropriate medical intervention. Identifying the underlying reason allows healthcare professionals to tailor treatment effectively, addressing the root cause of the immune response. While infections are the most common cause, considering other possibilities ensures a comprehensive evaluation.
