New study tests quick scan to spot swelling in cancer patients

This study explores whether a device that sends a tiny, safe electrical current through the body can better track fluid retention (edema) in cancer patients. Researchers will measure 46 people—breast cancer patients with arm swelling after radiation and others with leg swelling after chemotherapy. Participants will also give blood and urine samples and track their diet and weight. The goal is to find a more accurate, non-invasive way to monitor this common side effect.
