Lymph nodes are no bigger than baked beans, but they’re powerful weapons in the body’s defense against disease and infection. These ovoid glands are scattered throughout the body, helping filter impurities in the blood. Their mightiest role is producing B-cells, lymphocytes that make specialized proteins called antibodies to attack foreign invaders.
Sometimes, you may notice swollen lymph nodes in your neck, armpits, or groin. This is usually a sign that your immune system produces an abundance of B-cells to help your body fight off infection. But swollen lymph nodes may also signal more serious conditions.
This article will explain when swollen lymph nodes may indicate more than a common infection. Topics include:
- How do you know if swollen lymph nodes are caused by a severe condition?
- When should you call a doctor?
- Which tests may be used to determine why they’re swollen?
- Which cancers are associated with swollen lymph nodes?
