Primary and Secondary Lymphedema Care
Lymph is body fluid that is filtered from blood vessels to tissue. From tissue, lymph is transported by lymph vessels to lymph nodes and further via the lymphatic system back to venous circulation. If the lymphatic system is not functioning properly, lymph is unable to move forward and the tissue starts to swell with fluid. The swelling caused by the problems in the lymphatic system is known as a disease called lymphedema.
Lymphedema developed at birth is known as primary lymphedema. The lymph carrying capacity can also be diminished after surgeries, radiotherapy, trauma or infection. This is called secondary lymphedema. For example, in cancer surgeries the lymph nodes close to the tumor area are often either removed or radiated. The removed or damaged lymph nodes might predispose the body to lymphatic swelling.
