Lymphoedema is a type of swelling. It is an accumulation of lymphatic fluid, caused by a problem or blockage of the lymphatic system, that mostly occurs in the arms and legs but occasionally in other parts of the body.
Causes of lymphoedema include:
- primary lymphoedema — when people are born with an abnormality of the lymphatic system
- secondary lymphoedema — when there is damage to the lymphatic system. Common causes include surgery (including surgical removal of lymph nodes), trauma, radiation or infection
