Lymphoedema is the swelling of the limb/s and/or body, due to the accumulation of lymph The Lymphatic System Lymph is a colourless fluid, which forms in the body. It normally drains back into the blood circulation through a network of specialised vessels and nodes. Lymph nodes act as filter stations and they play important part in the body’s defence against infection. Why does Lymphoedema occur? If those specialised drainage routes through the lymphatic system are inadequate or become blocked or damaged, lymph (fluid) accumulates in the tissues and swelling (oedema) occurs. Unlike other oedemas – lymphoedema can lead to changes in the tissues such as fibrosis (hardness) and increased risk of infection. The swelling becomes even more difficult to control. Types of Lymphoedema Lymphoedema can develop as a complication in the treatment of cancer following surgery or radiotherapy. It can occur as result of infection, severe injury or trauma. Occasionally it is determined from birth and can be due to underdevelopment of the lymphatic system. It can then appear in infants or children and men or women at any age. more about Lymphoedema Treatment >
