Douglas upbeat over cancer battle
Actor Michael Douglas said he had begun treatment for throat cancer and that his odds of recovery were high.
In an appearance on David Letterman's Late Show, Douglas, 65, said he faced an "eight-week struggle" that included radiation and chemotherapy.
But the Oscar-winning Wall Street star, who is married to British actress Catherine Zeta-Jones, said he had at least an 80% chance of recovery.
Letterman told Douglas he looked good and was a "tough guy", and the men ended the interview with a hug, according to a CBS statement.
Douglas is currently starring in the upcoming Wall Street sequel Wall Street: Money Never Sleeps.
Talk show host Letterman said he was surprised after Douglas said he had just finished his first week of radiation and chemotherapy.
"You've never looked better to me, and this proves that you're a tough guy, for God's sakes," Letterman said, drawing cheers from the studio audience.
"Let's just say ... I'm pretty lit up right now," Douglas replied.
The disease was diagnosed three weeks ago, he said, although he had complained of a very sore throat earlier this year and had undergone testing that failed to find a cause.
Douglas, who has two children with Zeta-Jones, said he enjoyed the summer travelling with his family before returning to the doctor.
