A group of researchers collaborated to investigate using canine olfaction and chemical and nanotechnology analysis as a means of detecting early-stage ovarian cancer. ...
Volatile organic compounds (VOC) - or odorants, are altered in the early stages of ovarian cancer. The researchers say that previous studies have shown that trained detection dogs, alongside specific electronic devices, are able to detect minute quantities of odorants.
Patients from Penn Medicine, with and without ovarian cancer, have donated tissue and blood samples to the Working Dog Center to assist in their research.
Researchers at the University of Pennsylvania's Working Dog Center have started training three dogs to use their extraordinary sense of smell to sniff out the signature compound that indicates the presence of ovarian cancer.
The scientists theorize that if the dogs can isolate the chemical marker for the disease, they will then be able to direct scientists at the Monell Chemical Senses Center what to look for when developing an electronic sensor to find the same marker in women.
