How goes Patrick Swayze's battle with pancreatic cancer? "You can bet that I'm going through hell," Swayze tells Barbara Walters in an interview that airs on ABC tonight. "I'm at the beginning of my battle. And I expect it to be a long, hard battle, one that I'm going to win. I keep my heart and my soul and my spirit open to miracles. I pray." Swayze was diagnosed with stage four pancreatic cancer last January and acknowledges that his time may be running out. "I'd say five years is pretty wishful thinking," he said. "Two years seems likely if you're going to believe the statistics. I want to last until they find a cure, which means I better get a fire under it." During his cancer battle, Swayze has been filming a new series for A&E called The Beast, which stars him as an FBI agent fighting internal demons.
