Lymphedema is a condition that results from impaired flow of the lymphatic system. Symptoms of lymphedema include swelling in one or more extremities. The swelling may range from mild to severe and disfiguring.
Primary lymphedema is present at birth; secondary lymphedema develops as a result of damage to or dysfunction of the lymphatic system.
Breast cancer treatment is the most common cause of lymphedema in the U.S. While there is no cure for lymphedema, compression treatments and physical therapy may help reduce the swelling and discomfort.
