Lymphedema is a medical condition caused by an excess of fluid collecting in the interstitial tissue. When the lymphatic system is functioning normally, the interstitial fluid passes into the lymphatic capillaries, thought the lymphatic ducts, and returns to the circulatory system [1]. If this system is disrupted due to congenital reasons, surgery, or radiation therapy associated with cancer treatment, the fluid is unable to properly drain [2]. This collection of fluid leads to swelling of the affected area, usually the legs or arms (Figure 1).
