Summary

This study looked at whether a personalized meal plan with more omega-3 fatty acids (found in fish) could reduce fatigue, pain, depression, sleep problems, and stress in women who finished treatment for early-stage breast cancer 1-2 years earlier. Researchers enrolled 98 women and measured symptoms and inflammation markers before and after the 10-week diet plan. The main goal was to see if this type of study is feasible, not to prove the diet works.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Personalized meal plan (behavioral intervention)
What this could lead to
If successful, this could point toward a simple, cost-effective dietary strategy to help breast cancer survivors manage common lingering symptoms like fatigue and pain.
What could go wrong
This is a small, early feasibility study with only 98 participants. It cannot prove the diet works—it only tests whether such a study can be done. Results may not apply to all survivors.
