Lymphedema

Lymphedema occurs when lymphatic fluid builds up in the soft tissues of your body, usually in an arm or leg. The fluids can then build up and cause swelling in the affected arms or legs. There are two types of lymphedema: 1) inherited lymphedema, or primary lymphedema; 2) Acquired lymphedema or secondary lymphedema. Primary lymphedema is a rare inherited condition in which lymph nodes and lymph vessels are absent or abnormal. Secondary lymphedema can be caused by a blockage or cut in the lymphatic system, usually the lymph nodes in the groin area and the armpit. Blockages may be caused by infection, cancer, or scar tissue from radiation therapy or surgical removal of lymph nodes. The treatment program depends on the cause of the lymphedema. Medication cannot cure lymphedema. However, your physician may prescribe medications to treat associated conditions. For example, antibiotics play an important role in combating infections that can worsen lymphedema.
