Can Canines Smell CRC?

Jan. 31, 2011

Now that doctors have determined that a specific cancer scent exists, they may be able to use odor materials that could become effective tools in colorectal cancer screening.

Early detection and early treatment are of vital importance to the successful treatment of various cancers. The development of a novel screening method that is as economical and non-invasive as the fecal occult blood test for early detection of colorectal cancer (CRC) is needed. Doctors used canine scent detection to determine whether odor material can become an effective tool in CRC screening. The study, published in Gut, shows that a specific cancer scent exists and that cancer-specific chemical compounds may be circulating throughout the body. These odor materials may become effective tools in CRC screening. In the future, studies designed to identify cancer-specific volatile organic compounds will be important for the development of new methods for early detection of CRC.
