Lymphedema is an accumulation of lymphatic fluid in the interstitial tissue that causes swelling, mostly in the arms and legs. It develops when lymphatic vessels are missing or impaired (primary), or when lymph vessels are damaged or lymph nodes removed (secondary). When the lympathic fluid exceeds the lymphatic transport capacity, an abnormal amount of protein-rich fluid collects in the tissues of the affected area.

If this condition is not treated, the stagnant, protein-rich fluid reduces oxygen availability in the transport system, interferes with wound healing, and provides a culture medium for bacteria that can result in lymphangitis, an infection. Therefore, it is important for lymphedema sufferers to wear a lymphedema medical alert bracelet.

The lymphedema medical alert bracelet is also great for breast cancer patients after their surgeries. Those who have had lymph node dissection or radiation are at risk to develop lymphedema. Wearing the lymphedema medical alert bracelet is a proactive step to help survivors avoid this condition, and warm paramedics of the condition should a medical emergency occur.

The lymphedema medical alert bracelet can protect breast cancer survivors from receiving treatment to their affected arms) that could trigger the onset of lymphedema or worsen an existing case. In addition, the bracelet also provides a general awareness of the condition.
