This study was supported by the MACH Foundation (Fairfax, CA), Guide Dogs for the Blind (San Rafael, CA) and Frank and Carol Rosemayr (Kentfield, CA).
Purposetop

This study attempted to show that a canine could accurately detect certain types of cancer once trained to do so.

Summarytop

Trained canines can detect breast and lung cancer with 88% and 97% accuracy respectively.

Methods usedtop

Canines trained to detect cancer exhaled in breath were tested against samples from 86 cancer patients and 83 healthy control patients. The canines sat down next to a sample to indicate that the nearest sample contained the “cancer scent”.

Resultstop

The results showed that dogs can detect breast and lung cancer with sensitivity and specificity between 88 percent and 97 percent. The high accuracy persisted even after results were adjusted to take into account whether the lung cancer patients were currently smokers. Moreover, the study also confirmed that the trained dogs could even detect the early stages of lung cancer, as well as early breast cancer.

Notestop

This study fails to provide accuracy per breed or specific training methods, but the test results seem to indicate accurate training and therefore negates the relevancy of breed specific information.
