BEIJING, April 11 (CNN) -- In scientific experiments, dogs with super-sensitive noses can smell lung cancer blood in human blood samples with 97% accuracy, according to a newly released study. It is reported that the results of this experiment may provide a reference for cancer screening test in the future.
Three of the four two-year-old beagles were found to be able to correctly identify blood samples from lung cancer, with a success rate of 96.7%, the report said. The accuracy of detecting normal blood samples was 97.5%.
Dogs are able to do this because their noses are 10,000 times more sensitive to odors and their olfactory organs are 10,000 times more accurate than humans, according to the report.
Heather Junqueira, a researcher at BioScent Dx, Florida Pharmaceutical Laboratory, reported the findings and presented them at the annual meeting of the American Society for Biochemistry and Molecular Biology in Orlando on the 8th.
Although there is no cure for cancer, early detection offers hope for survival, Junqueira said. She said the study paved the way for further research into how dogsnoses can be used as cancer screening methods.
A highly sensitive test for cancer could save thousands of lives and change the way we treat related diseases, Junqueira said.
