The wastes are then filtered out by lymphocytes – infection-fighting cells that live in your lymph nodes – and eventually flushed from your body.

Lymphedema occurs when your lymph vessels are unable to adequately drain lymph fluid, usually from an arm or leg. Lymphedema can be either principal or secondary. This means it can occur on its primary lymphedema) or it can be affected by another disease or condition (继发性淋巴水肿). 继发性淋巴水肿是远远超过主要淋巴水肿更普遍.

癌症If cancer cells block lymphatic vessels lymphedema may result. For example, a tumor growing near a lymph node or lymph vessel could enlarge enough to prevent the flow of the lymph fluid.
Infection, An infection of the lymph nodes or parasitic, can restrict the flow of lymph fluid infection related lymphedema is most common in the tropical and subtropical region and is more likely to occur in developing countries.
