K9 Can Smell Out Lung Cancer

In an experiment by the German scientists that took place in London found that the sniffer dog can accurately detect lung cancer. By smelling breath samples, dogs were able to correctly detect lung tumors in 71% of patients.
“In the breath of patients with lung cancer, there are likely to be different chemicals to normal breath samples and the dogs’ keen sense of smell can detect this difference at an early stage of the disease,” said Thorsten Walles, who led the study and published its findings in the European Respiratory Journal.

Lung Cancer is the second most common cancer found in men and women across the world. Only in Europe it causes 340,000 deaths per year.
