NCT ID NCT06522971
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study looks at whether high-intensity interval training (HIIT) can improve how breast cancer patients respond to chemotherapy before surgery. Fifty-five patients will either follow a personalized HIIT program or maintain their usual activity level. Researchers will analyze tumor tissue and blood samples to understand the molecular changes caused by exercise.
