A calcified lymph node is generally not a cause for concern and since there are more than 500 lymph glands in your body, there's a lot of opportunity to acquire one.They are typically the result of an inactive, small, old infection that could have been caused by any number of things and then it remains there unchanged.our lymphatic system contains lymphocytes that work to protect you against bacteria, viruses, etc., that invade your body. An abnormal cell of this type does not cause a calcified lymph node but it can cause lymphoma. The primary jobs of your lymphatic system are: 1  Collect and then return interstitial fluid.
It is the role of these nodes to filter the lymph before it can be returned to the circulatory system. Although these nodes can increase or decrease in size throughout life, any nodes that has been damaged or destroyed, does not regenerate. 1  Afferent lymphatic vessels carry unfiltered lymph into the node. Lymph nodes also trap and destroy cancer cells to slow the spread of the cancer until they are overwhelmed by it. 2  Efferent lymphatic vessels carry the filtered lymph out of the node so that it can continue its return to the circulatory system.
