This swelling often seen in the hands and feet, severe swelling or a slight swelling. Any disorder of the lymphatic system may cause the accumulation of lymph fluid.

The risk of later composed lymphedema is higer after surgical procedures (particularly breast surgery), trauma and radiology. Lymphedema may might occur after a short period with the influence of those external factors, yet the most common type is seen months or years after.  Radiotherapy received after surgery is another risk factor. Medics should be warn about not to take blood from the corresponding arm, and not to measure blood pressure. To refrain from lymphedema, patients treated for breast cancer should avoid personally; to carry heavy, sun and heat exposure, to use a razor.
