1 Cancer. 2  If cancer cells block lymphatic vessels, lymphedema may result. 3  For instance, a tumor growing near a lymph node or lymph vessel could enlarge enough to block the flow of the lymph fluid. 4  Infection. 5  An infection of the lymph nodes or parasites can restrict the flow of lymph fluid.
When tumor cells block lymphatic drainage, fluid accumulates. If the blockage is located in the central lymphatic drainage system that drains chyle (milky fluid consisting of lymph and fat) to the thoracic duct, fluid rich in chyle accumulates in the pleural space.
