What is the most common cause of lymphedema in the United States?

The most common cause of lymphedema in the United States is post breast cancer surgery. This condition often arises as a result of surgical interventions that involve the removal of lymph nodes or damage to the lymphatic system during procedures such as mastectomy or lumpectomy. When lymph nodes are removed or injured, the normal flow of lymph fluid can be disrupted, leading to an accumulation of fluid in the surrounding tissues, which manifests as lymphedema.

Breast cancer is one of the most prevalent cancers affecting women, and the associated surgical treatments commonly lead to this complication. While other factors such as obesity, chronic venous insufficiency, and radiation therapy can contribute to lymphedema, they are not as common or direct a cause as the surgical treatment related to breast cancer. Understanding this association is crucial for health professionals in providing appropriate care and management for patients at risk of developing lymphedema following breast cancer treatment.
