Sniffing out cancer: dogs and polymers tested for breast cancer scent

NCT ID NCT04541537

First seen Jun 26, 2026 · Last updated Jun 26, 2026

Summary

This study explored whether breast cancer has a unique smell that can be detected. Researchers used a special polymer (Sorbstar®) and trained dogs to sniff samples from 35 women before and after tumor removal. The goal was to see if a distinct scent signature exists, which could lead to a new way to diagnose breast cancer.

What this could mean

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

What this could lead to

If successful, this could lead to a new, non-invasive way to detect breast cancer using scent.

What could go wrong

This was a very small, early feasibility study with only 35 participants. The results may not apply to everyone, and the method is still experimental.
