Definition of lymphedema

Lymphedema includes various conditions of localized fluid retention and tissue swelling caused by compromised lymphatic systems. It is most commonly caused by the removal or damage of lymph nodes as a part of cancer surgery, radiation therapy or infection, but it can be also seen in numbers of genetic disorders.

The main symptom of lymphedema is swelling of the affected arms or legs. And, it causes a feeling of fullness, heaviness, tightness, aching or discomfort, restricted range of motion, skin discoloration or thickening (fibrosis).

Certain infection may occur along with lymphedema, such as cellulitis, lymphangitis or lymphadenitis. Therefore, please tell your doctor right away if you have any symptoms of infection, such as redness, pain, heat, increased swelling, or fever.
