Lymphedema

Lymphedema refers to tissue swelling caused by an accumulation of protein-rich fluid that's usually drained through the body's lymphatic system. It most commonly affects the arms or legs, but can also occur in the chest wall, abdomen, neck and genitals. The lymphatic system is a part of the immune system and vital for immune function. Fluid called lymph circulates within the lymphatic system. Lymphedema is typically caused by a blockage of this system. Lymphedema is incurable, but with the right treatment, it can be controlled.
