4. Olfactory detection of human disease Basic scientific principle Metabolic diseases & cancers cause changes in body cells As these changes occur the cells produce volatile organic compounds (VOC’s) which the body needs to diffuse & excrete Each disease has it’s own VOC ‘fingerprint’ Dogs are trained to detect a specific fingerprint at very low concentrations 7

5. Canine Olfactory Detection Proof of principle Willis et al, (2004). Olfactory detection of human bladder cancer by dogs: proof of principle study, British Medical Journal, 329: 712. First clinically robust trial Demonstrated proof dogs could identify a unique odour associated with bladder cancer Cornu, et al, (2011) Olfactory detection of prostate cancer by dogs sniffing urine. A step forward in early diagnosis. J.Urology Sensitivity and sensitivity 91% / 91% 9
