Lymphedema

The term "edema" refers to the accumulation of an excessive amount of fluid in tissues or organs resulting in swelling. Lymphedema is the swelling of skin and subcutaneous tissue as a result of obstruction of lymphatic vessels or lymph nodes causing the accumulation of large amounts of lymph fluid in the affected region.

The two major types of lymphedema are primary lymphedema (a rare inherited condition) and secondary lymphedema which is caused by a blockage or interruption of the normal flow of lymph fluid through the lymphatic system.

A variety of risk factors have been recognized for secondary lymphedema including:

1. Breast cancer surgery
2. Cancer radiation therapy
3. Cancer of the lymph nodes
4. Infection
5. Chronic venous insufficiency
6. Fliarisis (a parasitic infection transmitted to humans by mosquito bites)

The objectives in the treatment of lymphedema include:

1. Control and reduce the swelling
2. Prevent progression of lymphedema
3. Prevent infection
4. Improve the patient's overall quality of life
   

Lymphedema can be treated.
