Cancer Sniffer
I've heard of sniffer dogs. They are dogs used by the police to trace
people buried beneath rubbles or those that sniff out bombs and drugs
in airports. But I've never heard of cancer sniffer dogs. These are
dogs trained to detect bladder cancer by smelling urine. Apparently,
cancer cells give off compounds that has a distinctive odor that dogs
can detect. Even skin cancers can be detected by these dogs by
(persistently) sniffing moles.
This is a breakthrough and it will further develop cancer detection.
Cheers to man's best friend!
