L-DEX Lymphedema Assessment/Measurement

Lymphedema is fluid build-up in soft body tissues when the lymph system is damaged or blocked. The result of lymphedema is swelling. Breast cancer lymphedema can often occur after lymph node removal surgery. Most lymphedema develops within three years of surgery. The chronic swelling from lymphedema can cause long-term physical, psychological, and social problems.

It has traditionally been challenging to detect and diagnose breast cancer-related lymphedema other than by observing swelling. Advances in bioelectrical impedance analysis (BIA) now allow physicians to measure lymph fluid changes and calculate a Lymphedema Index (L-DEX) ratio to assist with detection and proper diagnosis.
