Dogs watch us all the time and read our body language like a sixth sense. They also smell our bodies for changes.

Max smelt cancer in Maureen before any medical scans could pick it up. Dogs do this naturally and can be trained to pick up on tiny volatile chemicals given off by cancerous tumors. They can even be taught to alert diabetics to low blood sugar levels.

This dog can smell cancer

This is Frankie, a German shepherd mix. He can sniff out thyroid cancer in patients’ urine samples with 88% accuracy, according to a new study.

A trained scent dog accurately identified whether patients’ urine samples had thyroid cancer or were benign (noncancerous) 88 percent of the time, according to a new study by researchers at University of Arkansas for Medical Sciences (UAMS). The results were presented March 6 at the Endocrine Society’s annual meeting in San Diego.

Approximately 62,450 new cases of thyroid cancer will be diagnosed in the US this year, and around 1,950 Americans will die from the disease.

Techniques used to diagnose thyroid cancer include fine-needle aspiration biopsy, which involves the patient having a thin needle inserted into the thyroid gland in the neck to obtain a tissue sample. Donald Bodenner, MD, PhD chief of endocrine oncology at UAMS is the study’s senior investigator. Bodenner said:

Scent-trained canines could be used by physicians to detect the presence of thyroid cancer at an early stage and to avoid surgery when unwarranted.

Study-coauthor Arny Ferrando previously “imprinted,” or scent-trained, a rescued male German Shepherd-mix named Frankie to recognize the smell of cancer in thyroid tissue. Ferrando, who noted that dogs have at least 10 times more smell receptors than humans, said:

Frankie is the first dog trained to differentiate benign thyroid disease from thyroid cancer by smelling a person’s urine.

In this study, 34 patients gave a urine sample before they went on to have a biopsy of suspicious thyroid nodules and surgery. The surgical pathology result was diagnosed as cancer in 15 patients and benign thyroid disease in 19. These urine samples were presented one at a time to Frankie to sniff. Frankie had been trained to alert to a cancer sample by lying down, and turning away from a benign sample to alert the absence of cancer.

The dog’s alert matched the surgical pathology diagnosis in 30 of the 34 study samples, the investigators reported.

Bottom line: A new study by University of Arkansas for Medical Sciences (UAMS) researchers presented March 6, 2015 at the Endocrine Society’s annual meeting in San Diego described Frankie, a trained scent dog that accurately identified whether patients’ urine samples had thyroid cancer or were benign 88 percent of the time.

  1. Yes remarkable.. I saw on BBC the story of this… And how a little dog saved his owners life as they persisted in getting more tests done.. Alerted by their dog.. 🙂

    Have a Peaceful weekend.. and thank you for sharing

  2. Reblogged this on Dog Leader Mysteries and commented:
    Seems surprising at in the year 2015, we (humans) barely understand the abilities and innate talents of dogs. Dogs live in the present moment. They know instantly, using sensory abilities to smell and to hear, far beyond our awareness. Yet how many times to we say, “Stop barking, Go lay down.” to our dogs? Is if we (humans) know everything they smell and hear?

    Can you smell cancer? Dogs can. Can you pick out the scent of a single man from a mile over a huge city? Dogs can.

    Can you feel an earthquake coming four days before it hits?
    Four days before the 1906 earthquake shook the city of San Franscico, the horses and dogs knew something terrible would soon arrive. Most horses and dogs became uncontrollable, ran away or fought their caregivers.

    Time to listen to our dogs. Time to visit Paul’s constantly fascinating blog, Learning from Dogs. Thanks Paul for your permission to reblog this post.
