Humans have long harnessed the olfactory superiority of dogs for hunts and, more recently, to sniff out bombs, drugs and people during search-and-rescue missions. Now, scientists at the University of Pennsylvania are hoping to make early cancer detection the next frontier for canine-human collaboration. Inspired by previous research that found dogs could be trained to detect the scent of ovarian cancer in blood cells, the research team is working on a mechanical device – an ‘electronic nose system’ – to capture the same odour profile. Ultimately, the team hopes to develop a practical medical instrument to help doctors catch this deadly, elusive cancer earlier.
