Dogs trained to detect cancer in people

TAMPA, Fla. - An organization in Florida is training dogs to save lives by detecting cancer.      

The Pawsitive Life Foundation, based in Tampa, uses dogs that it rescues from shelters across the country and puts them through a 4-to-6-month training course.

The dogs can detect cancer because of their heightened sense of smell.

"They have about 250,000 times better scent than we do," said Tracy Eckert, a member of the Pawsitive Life Foundation.

Some studies say the dogs are 98 percent accurate in finding cancer.

The founder of the Pawsitive Life Foundation has firsthand experience on how important dogs are in finding cancer.

After her doctor told her that she was not sick, a dog detected that she had cancer. Tests proved the diagnosis and possibly saved her life.
