Exploring the Efficacy and Feasibility of the LymphaTech Scanner for Breast Cancer-Related Lymphedema Screening

Inclusion Criteria: * Participants must have histologically or cytologically confirmed invasive or in-situ carcinoma of the breast and will undergo unilateral breast cancer surgery * Age \>18 years. * Ability to understand and the willingness to verbally consent to the trial Exclusion Criteria: * History of primary lymphedema. * Any patient with a current case of cellulitis. * Participants with known brain metastases should be excluded from this clinical trial because of their poor prognosis and because they often develop progressive neurologic dysfunction that would confound the evaluation of neurologic and other adverse events. * Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements. * Participants unable to abduct upper-extremity perpendicular to body or to stand comfortably without aid for several minutes, both of which are necessary to perform a LymphaTech Scan
