Summary

This study tests whether taking a daily probiotic supplement for 6 months can reduce common chemotherapy side effects like nausea, vomiting, diarrhea, and nerve pain in breast cancer patients. One hundred women with stage I-III breast cancer will receive either a three-strain probiotic or a placebo. The goal is to see if probiotics improve quality of life and help patients complete their full course of chemotherapy.

What this could mean

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

Active substance
Probiotic (three-strain lactobacillus supplement)
What this could lead to
If it works, this could offer a simple, natural way to reduce nausea, diarrhea, and other chemo side effects, helping patients complete their treatment more comfortably.
What could go wrong
This is an early-stage trial with only 100 people, so results may not apply to everyone. Probiotics might not help, and some people could experience mild digestive upset.
