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.
A fluid called lymph, (lymph = clear fluid) flows in lymphatic vessels, lymphatic tissue and red bone marrow. Fluid filters out of capillaries and drains into lymphatic vessels to become lymph.The content of lymph is the same as interstitial fluid, the fluid around tissue cells.Lymph eventually drains into venous blood. Lymph drains interstitial fluid, transports dietary lipids and facilitates immune responses.econdary lymphoid tissues are also where lymphocytes are activated. These include: lymph nodes, tonsils, spleen, Peyer's patches and mucosa associated lymphoid tissue (MALT).
