What Causes Lymphedema And How Is It Treated

What Is Lymphedema

Lymphedema occurs when the lymphatic system is damaged or compromised, resulting in the disruption of the lymphatic flow (of lymph fluid) moving through the body within the lymphatic system. When this disruption occurs, there is a build-up of the lymph fluid in the fatty tissues just under your skin that causes swelling (edema), which is referred to as lymphedema.

In addition to swelling, the accumulated excess lymph fluid can cause your skin to become thickened or hardened, and creates a breeding ground for bacteria that makes the affected area susceptible to skin infections (cellulitis). If left untreated, the cellulitis can spread to the bloodstream and create potentially life-threatening conditions. The skin in the affected area may also become compromised, resulting in leakage of the lymph fluid, especially in cases where the skin is extremely swollen.

While you can be born with a compromised lymphatic system (primary lymphedema), most lymphedema occurs as a result of cancer treatment which is increases your risk of developing lymphedema as a result of the treatment (secondary lymphedema). Once it develops, lymphedema cannot be cured and instead must be treated through a process known as lymphedema Complete Decongestive Therapy CDT.
