Doctors freezing cancer tumors to slow their growth

ROCHESTER, Minn. -- Doctors at the Mayo Clinic in Minnesota are killing off cancerous tumors by freezing them.

The procedure, called cryoablation, was used on tumors that had spread to the lungs from other parts of the body.

Doctors use a probe to apply extreme cold, negative 148 degrees to the tumor.

They said it killed cancer cells for at least three months without affecting healthy tissue.

The procedure isn't a cure for cancer, but experts say it could help slow tumor growth.
