One of the most challenging morbidities after breast cancer treatment is lymphedema. Approximately 20% of women treated for breast cancer with axillary lymph node dissection will be diagnosed with lymphedema. Pre- and post-operatively, women are informed about changes suggestive of lymphedema and guided about seeking further assessment. The investigators presume that if symptoms occur, patients will seek assessment. However, it is unknown whether this is true or if those prospectively monitored present earlier for treatment, or whether other factors specifically drive patients to seek further assessment. Understanding the early experience and presentation of secondary lymphedema will improve patient education and detection programs.
