LELymphedema, also known as lymphoedema and lymphatic edema, is a condition of localized fluid retention and tissue swelling caused by a compromised lymphatic system, which normally returns interstitial fluid to the bloodstream. The condition is most frequently a complication of cancer treatment or parasitic infections, but it can also be seen in a number of genetic disorders.
