Dogs may be the key to detecting lung cancer early

Their sensitive noses can sniff out malignant odours

We know that dogs have an excellent sense of smell.

They are already helping rescue teams locate people in disaster areas and work with customs officers to identify contraband. Some have been trained to sniff out landmines.

In our research, we explore dogs’ ability to distinguish between people with and without lung cancer, using breath and saliva samples.

Our goal is twofold: we want to determine the potential for a scent-detection system for early lung cancer screening, and we hope to help develop a functional “electronic nose” for diagnosing lung cancer.
