Did you know pets can detect cancer????

Scientific reports of dogs sniffing out cancerous growths go back at least two decades. According to a 1989 case study in The Lancet, a patient reported that her dog would constantly sniff at a mole on her leg, and once even tried to bite the lesion off. Prompted by this, she had her mole checked out and found it to be a malignant melanoma.

But dogs are not only good at sniffing out skin cancer, some can also detect bladder, lung, breast, ovarian and colon cancer. In fact, a specially trained eight-year-old black Labrador named Panda correctly detected colorectal cancer in 33 out of 37 samples of people’s breath and stool that scientists had collected. Moreover, according to the article in the journal Gut published this year, Panda appeared to be highly accurate at detecting early-stage colorectal cancer.

It’s unclear whether such dogs are zeroing in on some unknown, tumor-related volatile compounds, or more conventional substances in body fluids associated with an increased risk of cancer, such as metabolites of cigarettes, the researchers said. However, in this experiment, Panda identified cancer patients even among body—fluid samples from people with inflammation, a history of smoking, or other diseases.
