On last night’s Late Show, Michael Douglas told David Letterman that he had Stage IV throat cancer, but his doctors are optimistic.

He shared that he had just completed his first of eight weeks of radiation and chemotherapy. He appeared thinner than usual and told Dave that in the coming weeks he voice will also change and he may not be able to swallow solid food.

He remained upbeat during the interview, saying that the cancer had not spread below his throat, adding that he has an 80% chance of recovery, with some doctors even more hopeful.

Letterman wanted to do something for the actor to which Douglas replied, ‘Aw, give me a hug!’ And the two embraced.

Douglas was appearing on the show to promote his latest project, Wall Street 2: Money Never Sleeps.
