Can a Plant-Based diet improve life for women with metastatic cancer?
NCT ID NCT07189702
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tests whether a whole food, plant-based diet combined with behavioral education can improve quality of life and diet adherence in 60 women with metastatic breast or endometrial cancer. Participants are randomly assigned to either the plant-based diet with support or a regular diet with standard wellness education. The main goals are to see if women can stick to the diet and if it helps them feel better.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- whole food, plant-based diet with behavioral education and support
- What this could lead to
- If successful, this could show that a plant-based diet helps women with advanced breast or endometrial cancer feel better and stick to healthier eating habits.
- What could go wrong
- This is a small, early-stage trial (60 participants) focused on feasibility and quality of life, not survival. The diet may be hard to follow, and results may not apply to all patients.
