LOS ANGELES – Dennis Hopper has been diagnosed with prostate cancer and is canceling all travel plans to focus on treatment, his manager said Thursday.

The 73-year-old actor and artist is being treated through a "special program" at the University of Southern California, said Sam Maydew.

Asked about Hopper's prognosis, Maydew said, "We're hoping for the best." He would not elaborate on the actor's condition.

Perhaps best-remembered for his role in "Easy Rider", Hopper recently finished shooting the second season of "Crash," a TV version of the Oscar-winning 2004 film. He plays maniacal music producer Ben Cendars on the series, which airs on the Starz network. Hopper also has several film projects in the works.

Nobody ever dreamed how popular Hopper would become when he and Peter Fonda finished filming the low-budget film "Easy Rider", however.
