Lymphedema
It is a swelling or ‘edema’ caused by a build up of fluid in the lymphatic system. Secondary lymphedema is what is seen in cancer patients after surgery to remove or dissect the lymph nodes in the arm, groin or pelvis. Normally the lymphatic system and the fluid of this system move to flight infection. Once the lymph nodes are removed fluid collects in the spaces between cell tissues. The buildup of fluid causes not only swelling but inflammation, pain and thickening of the skin in the area affected.
