Lymphedema

Lymphedema occurs when lymph (the fluid that flows through the lymphatic system) is unable to circulate and builds up in the body’s soft tissues—often in one of the arms or legs—and causes swelling. Other symptoms of lymphedema include a feeling of heaviness or tightness in the affected area, limited range of motion, and achiness. In breast cancer, lymphedema may develop following surgery and can also be a side effect of certain treatments such as radiation therapy. Lymphedema may develop within days of or even years after treatment.
