Current diagnostic thresholds vary, but a 5% volume difference between limbs is generally accepted to diagnose lymphedema. Newer research among women with breast cancer-related lymphedema established a 3% threshold for diagnosis of preclinical lymphedema. Understanding normal limb volume fluctuations and side to side differences is important to determine whether this 3% cut point for diagnosis of subclinical lymphedema should be made compared to same or contralateral limbs.
