Manual Lymph Drainage (MLD) is a primary tool in lymphedema management. Lymphedema is a condition of localized fluid retention caused by a compromised lymphatic system. Lymphedema can be inherited or caused by injury. It is frequently seen after surgery or radiation therapy, in which damage to the lymphatic system is caused during the treatment of cancer, particularly breast cancer. The goal of MLD is to improve or restore lymph drainage that has become impaired. MLD uses gentle massage-like techniques to stimulate lymph flow.
