Study shows dogs can accurately sniff out cancer in blood

Dogs have smell receptors 10,000 times more accurate than humans', making them highly sensitive to odors we can't perceive. A new study has shown that dogs can use their highly evolved sense of smell to pick out blood samples from people with cancer with almost 97 percent accuracy. The results could lead to new cancer-screening approaches that are inexpensive and accurate without being invasive.
