Whitfield’s cancer was discovered during a routine checkup, and is in its early stages. His doctors say it’s very treatable, and Andy says "I’m receiving excellent care, and am feeling strong, positive and determined with an army of support behind me."

The second season of Spartacus was scheduled to begin shooting next month, but has been postponed to accomodate Andy’s treatment. 

"Our thoughts and prayers are with Andy," says Chris Albrecht, President and CEO of Starz. "His health, of course, is our primary concern. He has our complete support during this difficult time." 

The first season finale of Spartacus airs on Friday, April 16.
