Disorders of the lymphatic system
The lymphatic system may not carry out its function adequately due to Obstruction in the lymphatic system leads to an accumulation of fluid ( Lymphedema ). Obstruction may result from scar tissue that develops when the lymph vessels or nodes are damaged or removed during surgery, by radiation therapy, by injury, or in tropical countries, by infection with a threadworm ( Infection may cause Swollen Lymph Nodes because the lymph nodes are inflamed. Sometimes the lymph nodes themselves may become infected ( White blood cell cancers such as Overview of Lymphoma can develop in lymph nodes, and tumors in other organs may spread (metastasize) to lymph nodes near a tumor. Cancers in lymph nodes can interfere with the flow of lymphatic fluid through the node. Cancers in other areas can block lymphatic ducts. Lymphangiosarcoma is a very rare tumor that may develop in cells of the lymphatic system.
