Michael Douglas ‘Very Optimistic’ About Cancer Battle

Michael Douglas is battling back against cancer.

Two weeks after revealing doctors had found a tumor in the actor’s throat, a rep for Douglas told Access Hollywood the star isn’t taking the diagnosis lying down.

“He’s a great fighter and very optimistic,” the rep told Access on Tuesday.

The rep also noted Douglas began his chemotherapy and radiation treatments “a week ago and has to do it for eight weeks.”

In a new interview with People magazine, Douglas showed off his determination to win his battle with the disease.

“I’m treating this as a curable disease,” Douglas told the mag, in an interview which will appear in the new issue of People later this week. “It’s a fight. I’ll beat this.”

Douglas is scheduled to appear on “The Late Show with David Letterman” on Tuesday night, where he will be promoting his upcoming film “Wall Street: Money Never Sleeps.”
