What is Lymphedema and how is it caused?
Lymphedema is a common disease which occurs in the lymphatic system. It is the swelling caused by the build up of lymph fluid, which may occur if the lymphatic system is damaged. It usually affects limbs (legs, arms) but the face/neck  may also be affected. In an extreme state the edema progresses. Skin becomes thicken with an appearance similar to elephant limbs.
It is most frequently seen after lymph node dissectionsurgery and/or radiation therapy, in which damage to the lymphatic system is caused during the treatment of cancer. However the exact cause is unknown. 

Unfortunately there are no cures for this, but it can be controlled. :( 



*Fun factIn 1929, German surgeon Werner Forssmann (1904-1979) examined the inside of his own heart by inserting a catheter into his arm vein and pushing it into his heart, inventing cardiac catheterization.
