Smartwatches track steps to predict breast cancer treatment success
NCT ID NCT07162675
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at whether the number of steps breast cancer patients take each day, tracked by a smartwatch, is linked to how well their treatment works. About 82 women with non-metastatic HER2-negative breast cancer will wear a Huawei Fit 2 smartwatch during chemotherapy before surgery. Researchers will compare step counts with tumor response after treatment.
