Scientists have come to an intriguing conclusion after a series of studies linking dogs and lung cancer. Several breeds of dogs were exposed to a merged group of people, individuals who were battling lung cancer and those who were healthy. The conclusions of this experiment revealed that there's a distinct scent connected with lung cancer patients that can be recognized by canines. In accordance with a Verterinarynews.com report, a scientific journal revealed that a particular VOC (volatile organic compound) is present in the breath of someone afflicted with lung cancer. The series of trials were conducted between December 2009 and April 2010.
The study
These studies contained over two hundred patients that were segregated into three different groups dependant upon their health condition. Of the two hundred and twenty individuals taking part in this study, one hundred and ten enjoyed a healthy body, 60 suffered with lung cancer and fifty subjects had chronic obstructive pulmonary disease (COPD). Patients suspected of cancer or struggling with other types of cancer weren't included in this analysis. The different breeds of canines that were taking part in this study were generally German Shepherds, and the remaining were Labrador retrievers and Australian Shepherds.
The results
Using the original theory that certain chemicals were generated in the breath of persons affected by lung cancer, these canines were exposed to the smells of all subjects. The success rate of this test was exceptional, with the dogs correctly identifying traces of lung cancer more than seven out of ten times. The 71% hit rate indicated that canines are efficient at determining lung cancer based on smell. Though the analysis demonstrated remarkably accurate results, these canines were not especially astute at knowing discrepancies between scents given out by smoking and COPD.
The challenges posed
Though the scientific study began in December 2009, this 6 month long research needed to be redone because the scientists observed a very important trait in the dogs. In the midst of the study, the scientists discovered that the canines were capable of memorizing scents of the various subjects. They then incorporated a new measure so that each dog was exposed to each smell only one time throughout the study. It was believed that the canines were not able to remember scents of over 200 patients in a period of 6 months. The accuracy and precision of the results shocked the scientists as a single scent could contain in excess of three thousand chemical compounds, indicating that canines had the distinctive capability of detecting lung cancer.
To delve deeper into this significant finding, the scientists now plan to confirm this theory by separating each scent and compound, and testing the dogs again. By using advanced sensor technologies, scientists hope to arrive at a proven conclusion. In addition they propose to explore whether canines are capable of revealing other types of cancer and their accuracy. At present, the researchers believe that the smell these wonder Labrador retrievers and German Shepherds are detecting could originate from the lung cancer medication given to the patients. Analysts aspire to reach a concrete conclusion after meticulously reviewing each scent given out by a chemical compound and each dog's ability to detect it.
