Dogs can sniff out breast, lung cancer
About a decade ago, a woman reported that she first became aware of her melanoma because her dog barked at the tumor. Now, scientists have been able to confirm that dogs can detect cancerous cells.
Researchers from the University of Negev in Israel have successfully trained dogs to differentiate cancer cells from non-cancerous in cell cultures. The dogs were trained to sniff out breast cancer cells, and were also able to identify lung cancer and melanoma.
After training, the animals were tested to determine if their abilities of detection were up to par. The scientists prepared five cell cultures, four of which were noncancerous and one that was malignant. The dogs were 100 percent accurate in determining the malignant cells for the three types of cancer.
According to the researchers, the next step is to check the dogs' reaction to people who have been diagnosed with cancer. Though the dogs were trained to detect cancerous cell cultures, the scientists believe there could be great potential in training dogs to detect cancer in people.
