Introduction to Lymphedema

The lymphatic system helps coordinate the immune system's function to protect the body from foreign substances and includes an extensive network of lymph vessels and lymph nodes. Here's how the lymphatic system works:

Excess fluid is collected from the space between tissues in the body and moves through the lymph vessels. The fluid (now called lymph) isn't pumped through the body like blood, but instead is "pushed" through the lymph system as the vessels are compressed by surrounding muscles.

Filters called lymph nodes remove certain harmful substances from the lymph fluid, such as bacteria and debris. The fluid from most tissues or organs is filtered through one or more lymph nodes before draining into the bloodstream.

What Is Lymphedema?

Lymphedema is an abnormal buildup of fluid that causes swelling, most often in the arms or legs. The condition develops when lymph vessels or lymph nodes are missing, impaired, damaged, or removed.

There are two types of lymphedema: primary and secondary. Primary lymphedema is rare and is caused by the absence of certain lymph vessels at birth, or abnormalities in the lymphatic vessels. Secondary lymphedema occurs as a result of a blockage or interruption that alters the flow of lymph through the lymphatic system and can develop from an infection, malignancy, surgery, scar tissue formation, trauma, deep vein thrombosis (blood clot in a vein), radiation, or other cancer treatment.
