The smell is a dog's primary sense containing 220 million cells. These receptors enable them to recognize various and serious illnesses. This ability sometimes outsmarts doctors.
In 1989 the British journal, Lancet, reported a woman with her dog who kept on sniffing a mole in her thigh and ignored other moles. This action leads her to consult a doctor and she later found out the mole was malignant melanoma. Due to various studies and evidence, it is believed that some dogs can identify normal skin from a cancerous one. After additional research, it was uncovered that tumors produce an aromatic compound called alkanes and benzenes, which are not present in healthy skin. This leads to a dog's superior ability to smell these differences.
Are dogs smarter than doctors? One study tests the dog's ability to identify which samples have abnormal skin tissues. It turns out that dogs are correct 99 percent of the time, compared to a human who is only correct 66 percent percent of the time. This study alone proves how man’s best friend can outwit the professionals in this particular scenario.
This is a powerful discovery since dogs can diagnose these differences without exposing them and human patients to harmful chemicals or radiation. This isn’t magic or myth. Other studies proved promising results about dog’s sensing ability when it comes to prostate cancer in men. By simply sniffing urine samples, dogs can detect multiple chemical combinations.
It is unlikely that canines will be joining the medical team any time soon. However, researches believe that well-trained dogs can add significantly to medical efforts in various fields!
