Enlarged Lymph Node

Enlarged lymph nodes, also known as lymphadenopathy, occur when the lymph nodes in the body become swollen and tender. Lymph nodes are part of the immune system and are responsible for filtering lymph fluid, trapping bacteria, viruses, and other foreign substances. When there is an infection, inflammation, or an immune response nearby, the lymph nodes can become enlarged as they work to fight off the invaders. Enlarged lymph nodes are most commonly felt in the neck, armpits, and groin area, but they can occur in other parts of the body as well.

​

In most cases, enlarged lymph nodes are a sign that the body is fighting off an infection. Common causes include viral or bacterial infections, such as the flu, common cold, or strep throat. However, there are also other potential causes, including autoimmune diseases, certain types of cancer, or even reactions to certain medications. If you notice an enlarged lymph node that is painful, rapidly growing, or accompanied by other concerning symptoms like weight loss or night sweats, it is important to seek medical evaluation. Your doctor will examine the area, review your medical history, and may order additional tests such as blood work or imaging to determine the cause of the lymph node enlargement and develop an appropriate treatment plan, which may include a surgical biopsy.
