Many people may dismiss swelling in an arm or leg, particularly if it's not painful. But if the swelling continues or keeps coming back, it could be a sign of lymphedema, a condition that affects the body's lymphatic system. The lymphatic system is responsible for draining excess fluid from body tissues. If this system is damaged or is not functioning correctly, fluid will accumulate, and lead to swelling. There are different causes of lymphedema such as some infections, injuries, congenital disorders and cancer therapies. Women who have had breast or gynaecological cancers may be at special risk if they had their lymph nodes removed or if radiation had been used. What are the WARNING SIGNS? Sometimes, lymphedema develops gradually. Signs and symptoms include swelling of one arm or leg, heaviness or tightness in the arm or leg, trouble putting on rings or a watch, and decreased movement in the arm or leg. At times, the skin can also be tight and turn into a hard consistency over time. In certain patients, a second infection of the skin may occur. These symptoms should not just be attributed to "normal swelling. An early evaluation may help determine the root cause and make the condition less complicated to deal with.

Treatment will depend on the severity of the disease and its etiology. Treatment usually involves compression garments, special physiotherapy, gentle lymphatic massage, exercises and skin care. The techniques may be used to help decrease swelling and movement. Surgery may be necessary in some cases of more severe or chronic lymphedema. New pathways can be created to allow the excess fluid to pass, such as in a lymphovenous bypass. For some patients, a transfer of lymph nodes or liposuction may be an option. Additionally, for patients who have an increased risk of developing lymphedema, doctors may also recommend preventive measures for individuals who must have some type of cancer surgery. This implies that measures should be taken to ensure protection of the lymphatic drainage before any appreciable swelling occurs.
