Did you know that trained dogs can detect many kinds of diseases simply through smell? For years, dogs have been able to detect different types of cancers, such as those of the lung, breast, ovarian, bladder, and prostate earlier than any other technology. In a study involving prostate cancer, for instance, trained dogs had a 99 per cent success rate in detecting the disease by sniffing patients’ urine samples. When trained to respond to samples from patients with one type of cancer, some dogs have detected several other types of cancer even where humans failed to identify similarities between the samples. “If you analyze the samples from, let’s say, skin cancer, bladder cancer, breast cancer and lung cancer, they have nothing in common,” says Andreas Mershin, a research scientist at the Massachusetts Institute of Technology.
