Fingernail moons may reveal who responds to breast cancer therapy
NCT ID NCT07590570
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether the small white moons at the base of fingernails (lunula) can predict how well breast cancer patients respond to chemotherapy before surgery. Researchers will track 188 patients to see if lunula status is linked to tumor disappearance and side effects. The goal is to find a simple, non-invasive way to personalize treatment.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
neoadjuvant therapy (chemotherapy before surgery)
What this could lead to
If successful, this could help doctors predict which breast cancer patients will benefit most from neoadjuvant therapy, personalizing treatment.
What could go wrong
This is an observational study, not a treatment trial. The link between lunula status and outcomes is unproven and may not lead to any change in practice.
