The New York Times recently reported on a program at the Penn Vet Working Dog Center that teaches dogs to sniff out cancer using positive reinforcement. A typical session finds a dog circling a wheel with 12 samples of blood plasma. Only one contains cancerous cells. When the dog halts in front of the correct sample, the trainer throws a tennis ball across the room and the dog chases it around giddily.
The Center utilizes dogs, known for their incredible senses of smell, to act as an early detectors of ovarian cancer. Dogs have also been shown to detect bladder cancer, melanoma, lung, breast, and prostate cancer. In the near future, interdisciplinary teams will isolate a range of cancer chemicals that only dogs can smell. Dogs won’t be entering the doctor’s office anytime soon, however. The ultimate goal is to manufacture nanotechnology that can detect cancerous tissue 1/100,000th the thickness of paper.
