Introduction: What Are Swollen Lymph Nodes?

Swollen lymph nodes, also known as lymphadenopathy, refer to the enlargement of lymph nodes, which are small, bean-shaped glands located throughout the body. Lymph nodes play a crucial role in the immune system, helping to filter out harmful substances and produce immune cells that fight infection.

When lymph nodes become swollen, it is often a sign that the body is fighting an infection or battling another underlying condition.
