The successful completion of this study will address whether bioimpedance analysis is a reliable, accurate method to measure pre-clinical and clinical lymphedema. In addition, we intend to evaluate whether bioimpedance analysis is better than the gold standard of volume displacement for measuring lymphedema. And most importantly, we will evaluate whether a short trial of compression garments in women identified to have pre-clinical lymphedema can actually halt the progression of disease. Bryn Mawr Hospital would propose to publish the research and findings of this study, which may have future bearing on the post-operative therapeutic management of subjects with pre-clinical lymphedema following axillary surgery.
