Background: Lymphedema has varied definitions, all based on limb volume changes. None incorporates limb volume changes, symptoms, and functional deficits. We will determine the incidence of lymphedema in breast cancer patients and the impact of breast conserving therapy, radiation therapy, sentinel lymph node biopsy, and axillary node dissection. The impact of lymphedema can be evaluated in a number of ways; 1) The Lymphedema and Breast Cancer Questionnaire (LBCQ) identifies symptoms that are unique to patients with lymphedema and 2) The Disability of the Arm, Hand, and Shoulder (DASH) survey will be used to determine the functional impact of lymphedema.
