Acting legend Dennis Hopper is losing his battle with prostate cancer after the deadly disease spread to his bones, according to a British report.

The Easy Rider veteran revealed his struggle with the illness in October, after he was admitted to hospital suffering from "severe flu-like symptoms."

He immediately underwent treatment at the University of Southern California, but doctors admit hopes for the 73-year-old are fading after the cancer spread, according to Britain's News of the World newspaper.

According to the publication, medics have informed Hopper - who has battled the disease since 2002 - that his cancer is incurable and that he may be facing his final days.
