PREVENT: PeRomEter Visualization to ENd Treatment-related Lymphedema

Primary Objectives: * To determine the effectiveness of prospective, intensive lymphedema screening in the postoperative setting using a perometer for reducing the cumulative incidence of grade lymphedema among breast cancer patients after ALND compared to routine screening. Secondary Objectives: * To estimate the direct costs associated with the Lymphedema Screening Initiative * To determine the association of the Initiative on patient productivity * To determine patient satisfaction with the Lymphedema Initiative in the context of their cancer care * To determine patient understanding of lymphedema-associated symptoms * To determine patient self-reported compliance with treatments and measures to prevent lymphedema * To determine the incidence of breast cancer-related lymphedema among a cohort of breast cancer patients treated with ALND To analyze clinical and pathological features associated with the development of lymphedema
