Do you know about Zoe and Liu, the bomb-sniffing dogs that can sniff out prostate cancer with more than 95% accuracy?
Animals can often provide love and support to patients with several kinds of conditions. Even autistic children develop better social skills when there is a pet in the household. They make great companions to man and dogs are one of the most favored kind to bring home as pets. Because of their remarkable sense of smell, dogs are also used in several professions. Hunting is a common sport that is done with the aid of dogs. Besides this, dogs have often been used alongside police and detectives to sniff out illegal substance, explosives and blood. Research conducted on their soggy noses recently found that they can also sniff out different kinds of cancers, especially prostate cancer, with over 95% accuracy.
Frankie, a German shepherd-mix dog that could diagnose thyroid cancer in urine samples, was a favorite among many when he was in the news recently. Frankie had a remarkable 88% success rate at identifying the correct samples that contained the cancer. The latest news is that two female German shepherds, Zoe and Liu, were trained to detect prostate cancer. The results were published in The Journal of Urology and said that the trained dogs were able to achieve more than 95% of accuracy in detecting the urine samples.
The current prostate cancer detection tests involves a blood test that identifies a protein known as prostate-specific antigen (PSA). The prostate gland creates these PSAs and a high level of these cells can denote the presence of prostate cancer. While PSAs naturally occurs in our blood in tiny amounts, sometimes other conditions like urine infections and inflammations can also cause high PSA levels. Because of the possibility of so many conditions, the current test based on PSA levels alone is not promising enough and so other tests like physical examinations and biopsy surgeries may also be required before diagnosing prostate cancer.
