During the 1990’s there was a dog in Florida that was trained to, and became very adept at, detecting melanoma skin lesions. And in fact, during his career in melanoma detection he had ID’d positive on a melanoma lesion that a human pathologist had missed!

cancer sniffing and bomb detection.
This was Ch. & OTCh Tailgates George VonPickel, UDX
George was owned, trained, handled and loved by a fellow who had retired from a long career training scout dogs in the military. (IOW, he was a highly experienced dog trainer).
Upon returning to civilian life he had joined the Tallahassee, FL P.D. and then pursued getting a dog with the aim of having a dog that would be able to be trained as his aide/side-kick for police work. He was accustomed to working with larger dogs such as German Shepards etc. in the military, but he wanted a somewhat smaller dog, hence this dog was chosen.
For some specific reasons this particular dog had some limitations for general police work, but (as is obvious by his titles there) he had been fully obedience trained -- which meant that he had learned and mastered scent discrimination skills. So scent discrimination work, and its various applications, was the direction that was to be pursued with George.
AND WHOW – did he ever achieve. He was used in explosives detection work throughout the SE USA, saw service in sweep detection work and general guard duties for events with dignitaries such as the President of the US, -- as well as various and sundry other scent oriented duties and challenges.
His unique claim to fame came though in his seemingly uncanny ability, and highly reliable skills, in detecting and differentiating melanoma from other skin lesions.
George has of course, long ago now, crossed the Rainbow Bridge.
Since training numbers of dogs to work in dermatology to aide in melanoma detection is an unreasonable aim --- this endeavor was taken into the labs at the University with the aim of attempting to analyse, and discover, exactly what it is in this kind of abnormal tissue growth that the dog could accurately sort out and identify as this specific neoplasm.
However to date – with all the sophisticated technology and equipment in the mass spectrometry rhelm of laboratory exploration, researchers have not been able to find the specific chemical that yields the specific scent marker for this type cancerous growth.
Human brain power, and ingenuity – and with all manner of sophisticated equipment, has not been able to identify what the dogs olfactory organ can be trained to recognize.
George was a canine pioneer in cancer scent detection work. And to this day, --- the dogs nose still reigns supreme. The canine olfactory systems great potential goes largely untapped today.
