Chronic swelling caused by lymphatic system damage or blockage
Lymphedema is a chronic condition where the lymphatic system fails to drain lymph fluid adequately, leading to swelling — most commonly in the arms or legs. It can be primary (due to developmental abnormalities) or secondary (following cancer treatment, surgery, or infection).
Diagnosis involves clinical assessment, lymphoscintigraphy, MRI lymphangiography, and ICG (indocyanine green) lymphangiography.
Seek care if you notice unexplained swelling in an arm or leg, especially after cancer treatment or surgery. Early intervention prevents progression.
