In an appearance Tuesday on David Letterman's "Late Show," the actor said he faces an "eight-week struggle" that includes radiation and chemotherapy. Douglas said he has at least an 80 percent 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 stars in the upcoming film "Wall Street: Money Never Sleeps," a sequel to "Wall Street" (1987), for which he won a best-actor Oscar.
