Lifestyle makeover may boost breast cancer treatment success
NCT ID NCT07066189
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a structured nutrition and exercise program can improve the chance of a complete response to pre-surgery chemo-immunotherapy in women with triple-negative breast cancer. About 160 women who are not currently exercising or eating many fruits and vegetables will be randomly assigned to either the lifestyle program or usual care. The goal is to see if those in the program have no cancer remaining in the breast or lymph nodes at the time of surgery.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- exercise and medical nutrition program
- What this could lead to
- If it works, this could show that a structured lifestyle program helps more women achieve a complete response to pre-surgery treatment for triple-negative breast cancer.
- What could go wrong
- This is a relatively small, early-stage behavioral trial, so results may not be conclusive or widely applicable. The intervention is added on top of standard treatment, so its independent effect may be hard to measure.
