Pre-existing Factors, Early Detection and Early Treatment of Breast Cancer Related Lymphedema

Breast-cancer related lymphoedema (BCRL) is a common phenomenon. Early diagnosis and treatment is very important to alter the normal progression of this disease. A threshold (\>= 3% volume change) that recognizes subclinical lymphedema is promoted. When the lymphedema is diagnosed late, options for treatment are diminished as fibrous tissue is formed. Preoperative investigation with near-infrared fluorescence lymphography can show an abnormality. Even if a linear transport is visualized, velocity of the transport can be diminished or a different pathway than normal can be visualized. Such an extensive evaluation has not been performed yet. This lymphofluoroscopy gives an opportunity to detect lymphedema earlier than clinically visible (subclinical). The investigators hypothesize that the evolution of lymphedema can be altered if treatment is started in the subclinical phase.
