Scientists have successfully identified the sensory power of dogs to smell out cancer by challenging them with breath samples from patients with lung and breast cancer. Experts believe that cancers in the body produce different metabolites to healthy people, which can be detected in their breath, and identified by trained dogs. The study revealed that the dogs' detection rate was 90% correct. The hope is that dogs will be able to assist with early investigation for cancer.
