Summary

This study is testing whether a probiotic called BIOHM can change the community of bacteria and fungi (the microbiome) in the breast and gut of people with breast cancer. Researchers will measure certain biomarkers in 100 participants to see if the probiotic has an effect. The goal is to better understand how microorganisms relate to breast cancer, which could lead to new prevention or treatment strategies.

What this could mean

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

Active substance: probiotic (BIOHM)
What this could lead to: If successful, this could reveal how probiotics affect the microbiome in breast cancer, potentially pointing toward new ways to prevent, diagnose, or treat the disease.
What could go wrong: This is an early-stage study focused on measuring biological changes, not on curing or treating cancer directly. The probiotic may have no significant effect on the microbiome or cancer outcomes.
