Actor Patrick Swayze is responding well to his treatment for pancreatic cancer. The star of "Dirty Dancing" and "Ghost" announced last month that he was diagnosed with pancreatic cancer, one of the most serious of the cancers.

On Tuesday, his physician, Dr. George Fisher, announced that Swayze has had an "excellent" response to treatment. He added, "Patrick Swayze continues to respond well to his treatment for pancreatic cancer. Because of his excellent response, he will continue the same therapy at Stanford."

Swayze, 55, has been undergoing chemotherapy but not radiation treatment.

Swayze's wife, Lisa Niemi, told People.com, "We're thrilled and grateful for the positive response Patrick has shown towards his treatment. Also, we can't help but feel that all the prayers, meditations and good thoughts sent his way by everyone has made a difference. Thank you."
