Lymphedema is a swelling of some area of the body, typically an arm or leg, resulting from an accumulation of lymph fluid. Lymph, the transparent waste fluid that is collected from body tissues, is normally removed via the lymphatic system.

However, in lymphedema, the body's ability to circulate lymph is compromised. Instead of the usual transport of lymph fluid from the lymphatic system to the circulatory system where it can be utilized or removed, the lymph fluid accumulates and causes swelling, pain and increased chance of infection within the affected limb.

Untreated, lymphedema can cause permanent loss of limb function, skin breakdown, chronic infection and even a lymphatic cancer known as lymphangiosarcoma.

Treating Lymphedema 

Lymphedema is caused by a defect or damage within the lymphatic system.

PRIMARY LYMPHEDEMA is a genetic condition linked to a physical defect in the lymphatic vessels or nodes. Primary lymphedema may appear shortly after birth, develop at adolescence or even after age 35. Primary lymphedema may be triggered by some physical trauma that overloads the lymphatic system, such an infection, injury or allergic reaction.

SECONDARY LYMPHEDEMA is more common and occurs after a trauma involving the lymph nodes, such as breast, uterine, or prostate cancer surgery or radiation treatment. Secondary lymphedema can appear immediately after a medical procedure or it may occur months or even years later.
Secondary lymphedema is difficult to predict, so it is extremely important that each individual at risk for developing lymphedema be educated about the factors that can trigger or aggravate the condition.
