About Lymphedema
Secondary Lymphedema
Secondary lymphedema
is caused by injury or scarring to the lymph vessels or removal of the
lymph nodes. It most commonly occurs as a result of surgery or radiation
to the lymphatics. Such treatments are commonly given for cancers of
the breast, uterus, bladder, ovary, prostate, testicles and for malignant
melanomas and lymphomas.
Secondary lymphedema
may also result from a trauma, a crush injury, hip or knee surgery,
amputations, blood clots, vein grafts from cardiac surgery, chronic
infections, or longstanding circulatory problems such as chronic venous
insufficiency or diabetes.
It is estimated
that there are over two million cases of secondary lymphedema in the
U.S., most the result of breast cancer treatment. Estimates place the
incidence of lymphedema at 20%-25% following removal of lymph nodes
for treatment of breast cancer. Radiation increases the risk of developing
lymphedema by about 25%.
