Noninvasive Assessment of Lymphedema Among Breast Cancer Survivors

This proof of concept study will evaluate the ability of a new, ultrasound based technology called Bullseye Constructive Shearwave Interference (CSI) (trade name, Bullseye Elasticity Quantification) to measure lymphedema of the upper arm among breast cancer survivors. The study's hypothesis is that the CSI device can detect the presence of clinically significant lymphedema when compared with the standard arm tape measurement.
