Patrick Swayze's cancer has reportedly spread to his liver.

The 'Dirty Dancing' star - who announced earlier this year he is suffering from pancreatic cancer - has started preparing himself for death by saying goodbye to his friends and family after discovering the deadly disease has infected another part of his body.

A source told National Enquirer magazine: "Patrick recently got word that the cancer had spread to his liver and that is what his doctors said would begin the countdown to the end. Patrick knew it was coming because he was suffering increased weakness.

"At times, he was so weak that he could barely walk without feeling faint. Sometimes he feels out of breath and has to sit down."

Patrick, 56, has reportedly told Lisa, his wife of 33 years, and his brother Donny that he doesn't have long to live.

The source added: "Lisa phoned Donny in Los Angeles and told him he need to come to Chicago, where Patrick has been filming TV show 'The Beast'. She was crying and scared Donny to death.

"Donny got the impression his brother was already on his deathbed because Lisa was saying Patrick wanted to say goodbye. She couldn't stop crying."

Patrick has been undergoing pioneering Cyberknife radiotherapy at California's Stamford University Medical Center, and had been making a steady recovery from the illness.
