Benign to malignant: Lymphadenopathy is a common symptom

Lymphadenopathy means enlarged lymph nodes, which are often accompanied by tenderness, redness, and warmth at the location of the swollen node. It can occur in a broad range of benign and malignant conditions, from exposure to a virus to cancer. Lymph nodes are present throughout the body, mostly at points of entry and drainage in the lymph system, so swollen nodes indicate an active immune response. Depending on the cause, lymphadenopathy can be localized or generalized.
