Study: dogs can accurately detect colon cancer


Some day, when you go for your annual medical check-up, a Labrador Retriever may help perform your cancer screenings.

Dogs can detect even hard-to-find early stage bowel cancer, according to a new study published in the international gastroenterology journal, Gut Magazine.

The new scientific study has proven that canine scent detection can become a highly accurate tool in colorectal cancer (CRC) screening. A Labrador Retriever specifically trained in cancer detection helped researcher prove that a specific cancer scent does indeed exist and that these odor-producing materials may become effective tools in CRC screening.

Dogs already detecting even earliest stages of many cancers
While training cancer-sniffing dogs is expensive and unwieldy for widespread use, the study, designed to identify cancer-specific volatile organic compounds will be important for the development of new methods for early detection of CRC and other forms of cancer.

Colorectal cancer is the fourth most most common cancer in men and women in the U.S., according to the National Cancer Institute.

Several breeds of dogs already have been trained to accurately identify cancers including those of the skin, lungs, breasts, ovaries, prostate, and bladder by sniffing the person’s breath or urine. Among their remarkable abilities: they can sniff out even the earliest, hardest-to-detect stages of these cancers.
