What is Lymphedema?
Lymphedema is an abnormal accumulation of protein-rich fluid (edema) within the skin. It can be caused by damage to lymph circulation from cancer treatments or trauma, or by hereditary conditions. Lymphedema most often affects the arms or legs, but can occur in other regions. This can become a chronic, progressive problem if untreated. Low level laser may be used by medical care providers as a part of a program of comprehensive therapy.
Low Level Laser Therapy
Low level laser therapy (LLLT) or “cold laser” has been used in clinics for over 40 years. A beam of infrared light is absorbed by body tissues, and causes beneficial physiological changes due to photochemical and photophysical processes. In 2006, the FDA approved the RIANCORP LTU 904 for treatment of post-mastectomy lymphedema. It is the only laser cleared for treating lymphedema. Click here for a detailed video presentation.
Scientific Studies
Low Level Laser: Flinders Medical Centre in South Australia conducted the only randomised double blind trial for any lymphedema treatment in the world. They studied the RIANCORP LTU904 device without any adjunctive therapy. Results were impressive: 30% of patients had a significant reduction in limb volume that was maintained (or improved) for 3 months. The study was published in the journal “Cancer” in 2003.
