Lymphedema: An overview When the lymphatic system is disturbed it can no longer take up sufficient lymph fluid. The fluid accumulates in the tissues. The result: a visible and palpable swelling. Doctors call this lymphedema. • Disturbances of the lymphatic system can be primary (congenital, praecox or tarda) or secondary (operations such as due to cancer, radio therapy, infections, or injury). • Lymphedema can occur locally or over the whole body (generalized lymphedema). • Lymphedema is a chronic disorder.
