Dirty Dancing's Patrick Swayze has been diagnosed with pancreatic cancer, says his doctor, confirming reports in the New York Post and the National Enquirer. "Patrick has a very limited amount of disease and he appears to be responding well to treatment thus far," Dr. George Fisher says in a statement. "All the reports stating the time frame of his prognosis and his physical side effects are absolutely untrue. We are considerably more optimistic." His rep adds, "Patrick is continuing his normal schedule during this time, which includes working on upcoming projects. The outpouring of support and concern he has already received from the public is deeply appreciated by Patrick and his family." The actor shot a pilot in December called The Beast, which may be picked up as a series by A&E.
