lymphedema
(LIM-fuh-DEE-muh) - A condition in which lymph builds up in tissues and causes swelling. Lymphedema usually affects an arm or leg, but it can also affect other parts of the body. Lymphedema can occur when lymph vessels or nodes become damaged or blocked, which affects the flow of lymph in the body. This is most commonly caused by cancer or cancer treatment, such as surgery or radiation therapy. It can also be caused by infection with certain parasites or by having certain inherited conditions in which the lymph nodes or lymph vessels are abnormal or absent. Lymphedema cannot be cured, but treatment can help relieve swelling, pain, and other symptoms.
