Study of Lymphatic Dysfunction in Primary and Secondary Lymphedema

Lymphedema is a disorder of the lymphatic vascular system characterized by impaired lymphatic return and swelling of the extremities and accumulation of undrained interstitial fluid/lymph that results in fibrosis and adipose tissue deposition in the affected area. It can be an inherited condition (primary lymphedema) or occurs after cancer surgery and lymph node removal (secondary lymphedema). It causes a significant morbidity and is a common disabling disease affecting more than 200 million people worldwide, however there is no curative treatment for primary or secondary lymphedema.
