What is Lymphedema?
Lymphedema After Treatment
Lymphedema is a problem that may occur after cancer surgery when lymph nodes are removed. Lymphedema can occur months or years after treatment. It’s a chronic (ongoing) condition that has no cure.
But steps can be taken to help keep it from starting, and to reduce or relieve symptoms. If left untreated, lymphedema can get worse. Getting treatment right away can lower your risk of infections and complications.
How Lymphedema Happens:
During surgery for cancer, nearby lymph nodes are often removed. This disrupts the flow of lymph, which can lead to swelling. This is lymphedema. Lymphedema can affect one or both arm, the head and neck, the belly, the genitals, or the legs. Swelling can worsen and become severe. Skin sores or other problems can develop. Affected areas are also more likely to become infected.
Often during breast cancer treatment, some or all of the lymph nodes under the arm are treated with radiation. The lymph nodes under the arm are also called the axillary lymph nodes. They drain the lymphatic vessels from the upper arms, from most of the breast, and from the chest, neck, and underarm area.
When many lymph nodes under the arm have been removed, a woman is at higher risk of lymphedema for the rest of her life.
Radiation treatments to the under arm lymph nodes can cause scarring and blockages that further increase the risk of lymphedema. Lymphedema may occur right after surgery or radiation, or months or even years later.
