Cancer-sniffing dog being cloned in S Korea

SEOUL (AFP) - A Japanese centre which says it has trained a dog to sniff out human cancer cells is cloning the animal in South Korea, a Seoul bio-technology company and the dog's owner said Wednesday.

Cloned foetuses from the black labrador retriever named Marine were last month implanted into a surrogate mother dog, said Ra Jeong-Chan, president of RNL Bio.

Researchers in several countries are investigating whether dogs have the ability to detect lung, breast, prostate and skin cancer at an early and treatable stage.

They believe cancer cells create a scent not present in healthy cells, which can theoretically be picked up by dogs in breath or urine samples.
