 FACT: When Bob Gerson gives Frank Corbin Hawks medical file showing  that Hawk has pancreatic cancer, the document that shows the  diagnosis is an electrocardiogram (EKG). That device is used to  measure the electrical activity of the heart (thats the squiggly  lines with peaks and valleys you see as Frank looks over the  document before zeroing in on the diagnosis); not a test for cancer.  Such a diagnosis would never be put on an EKG for any reason.
