Dennis Hopper diagnosed with prostate cancer, cancels travel for treatment.

Iconic  actor, director, producer, writer and artist Dennis Hopper has prostate cancer and is canceling all travel plans to focus on his treatment.

His manager, Sam Maydew, tells Access Hollywood that the 73-year-old actor and artist is being treated through a "special program" at USC.

Hopper missed an exhibition at the Australian Centre for the Moving Image in Melbourne called "Dennis Hopper and the New Hollywood," a collection of his artwork and photos.

Hopper recently finished shooting the second season of the Jerry Bruckheimer TV series "Crash" and has several film projects in the works.

Good luck, Dennis. We know you can beat this.
