Objective/Hypothesis: Our hypotheses are: 1) Local therapies for breast cancer result in different lymphedema rates depending on the combination of therapies used. 2) A simple screening tool that incorporates symptoms, limb volume measurements, and tumor staging and treatment modalities can predict those patients that will develop lymphedema. 3) Functional impairment of the arm is severe in patients with lymphedema. 4) Prevention of lymphedema in a high risk population is possible with education, a compression sleeve, and decongestive exercise.
