Lymphedema is also known as Lymphatic obstruction. Lymphedema is caused by a blockage in your lymphatic system, an important part of your immune and circulatory systems. The blockage prevents lymph fluid from draining well, and as the fluid builds up, the swelling continues. Lymphedema is most commonly caused by the removal of or damage to your lymph nodes a part of cancer treatment. There is no cure for lymphedema, but it can be controlled.

This means it can occur on its own (primary lymphedema) or it can be caused by another disease or condition (secondary lymphedema). Secondary lymphedema is far more common than primary lymphedema. Primary lymphedema causes include Milroy’s disease, Meige’s disease, and late onset lymphedema. Both Milroy’s disease and Meige’s disease are both hereditary disorders. Secondary lymphedema causes include surgery, radiation, infection, and cancer. Pretty much any condition or procedure that damages your lymph nodes or lymph vessels can cause lymphedema.
