Can dogs smell cancer?

Topics: Medicine

A new study that will be published in the March 2006 issue of the journal Integrative Cancer Therapies, shows that dogs have the ability to distinguish breast and lung cancer in people compared to healthy controls. Researchers revealed scientific evidence that a dog's extraordinary scenting ability can distinguish people with both early and late stage lung and breast cancers from healthy controls. The work was performed in California, and was recently documented by the BBC in the United Kingdom, and is soon to be aired in the United States.

The clinical implications of canine olfaction first came to light in the case report of a dog alerting its owner to the presence of a melanoma by constantly sniffing the skin lesion. Subsequent studies published in major medical journals confirmed the ability of trained dogs to detect both melanomas and bladder cancers. The new study, led by Michael McCulloch of the Pine Street Foundation in San Anselmo, California, and Tadeusz Jezierski of the Polish Academy of Sciences, Institute of Genetics and Animal Breeding, is the first to test whether dogs can detect cancers only by sniffing the exhaled breath of cancer patients.
