Lymph Nodes in the Breast

Lymph nodes are small glands located throughout the body that help filter the lymph. They play an important role in immunity. The lymph is a clear fluid that circulates the lymphatic system, allowing the body to get rid of germs and waste products. When an infection occurs in the body, a signal occurs as chemical changes occur. The lymphatic system detects the changes and fights the infection.
