This article explains the causes and significance of swollen lymph nodes, exploring how infections, injuries, and tumors can lead to enlargement. Recognizing symptoms like tenderness and swelling helps in early detection of underlying health issues, prompting timely medical evaluation. Understanding lymph node health is crucial for maintaining immune system function and overall wellness.

Signs and Causes of Enlarged Lymph Nodes

The lymphatic system is vital in defending the body against infections. Lymph nodes, small bean-shaped organs, facilitate the movement of lymph fluid, nutrients, and waste between tissues and blood vessels. They serve as filters, trapping harmful pathogens and aiding immune responses. Enlarged lymph nodes, known as lymphadenopathy, commonly occur in areas like the neck due to infections, injuries, or sometimes tumors developing nearby.

Since lymph nodes are key to immune health, any swelling should be checked promptly. Factors include infections and tumors involving vital organs such as the lungs, breasts, neck, or abdomen. For example, swelling above the collarbone points to issues with supraclavicular nodes. Infections in the legs, feet, or genital regions can also cause swelling of inguinal or femoral lymph nodes.

Swelling in neck lymph nodes often indicates immune system activity. Common signs include tenderness, swelling, and discomfort. Respiratory infections may bring about sore throat, fever, and nasal congestion, while persistent swelling or night sweats can suggest serious issues like tumors or immune conditions. Since lymph nodes are central to immune defense, persistent enlargement should be evaluated by a healthcare professional to identify the cause, whether benign or severe.
