Information on Lymphedema for Patients(For more information, consult the NLN Position Papers at www.lymphnet.org) Definition:Our bodies have a network of lymph nodes and vessels that carry and remove lymph fluid, similar to how arteries and veins circulate blood to all parts of the body. The lymph fluid contains white blood cells that help us fight infections. Lymphedema is the build-up of lymph fluid that causes swelling in the legs, arms, breast, trunk, torso, head, or neck. In cancer patients, lymph node removal changes the way lymph fluid flows within the side of the body affected by removal. This change makes it more difficult for fluid in one body part to circulate to other parts of the body. If the remaining lymph vessels cannot remove the fluid, it builds up, causing lymphedema. You are at risk for lymphedema if your lymphatic system is damaged or altered by surgery and/or radiation, injury, burns, infection, and other causes, or have inherited genetic anomalies, gene mutations, or developmental problems of the lymph system in utero. Your risk may change depending on weight gain, degree of scarring, and other factors. Diagnosis of lymphedema requires evaluation by a trained physician. |
