We all know that dogs are great for fellowship and encourage us to get out of the couch and go for a walk, but here's another reason to love them. According to recent research, the best friend of man is able to detect cancer in blood samples.
For the study, which was conducted by Florida-based research firm BioScentDx, it was taught to four Beagles to use their sense of smell to distinguish the blood of healthy people from that of patients with Alzheimer's disease. a malignant lung cancer. After training, three of the dogs identified lung cancer samples in 96.7% of the cases and normal samples in 97.5% of the cases. The fourth dog, Snuggles, had no interest in playing (we forgive you, Snuggles).

"This work is very interesting because it opens the door to new research in two ways, both of which could lead to new cancer detection tools," said Heather Junqueira, Research Director. "One uses canine fragrance detection as a method of cancer screening and the other is to identify the biological compounds that dogs detect and then develop cancer screening tests based on these compounds."
Early detection of cancer offers patients the best hope for survival, and sensitive and cost-effective testing could help save many lives. BioScentDx wants to use dogs to create non-invasive methods of screening for cancer and other diseases. Late last year, the company launched a study in which patients with bad cancer submitted breath samples to screening tests by detector dogs.
Dog odor receptors are about 10,000 times more accurate than ours, which means they can detect odors that are simply unnoticeable. Of all dog breeds, Beagles have some of the best noses, which means they are brilliant (sorry) for detecting diseases, prohibited substances and explosives.
