Lymphedema is the chronic or persistent swelling of a body part due to an obstruction of the lymphatic system. The lymphatic system lies underneath the skin and works closely with the blood circulation system as it transports fluids throughout the body to lymph nodes. While in the lymph nodes, the fluid is “cleaned” of bacteria, viruses, and other unwanted materials. The “clean” fluid is then sent to the blood and re-circulated throughout the body. Lymphedema occurs when the lymphatic system is damaged and unable to move the fluid, therefore the fluid collects in the body part and swelling develops. Damage to the lymphatic systems occurs when there is surgery, mastectomy, lymph node removal, radiation, or injury to skin tissue (such as a burn).
