Dennis Hopper opened up on Saturday about how he's been feeling since his manager's announcement last month that he'd been diagnosed with prostate cancer.

Hopper, who was attending the Breeders' Cup horse-racing event in support of The V Foundation for Cancer Research, told the Associated Press he's begun receiving a new, experimental treatment at the University of Southern California that he believes has "great promise," and he added, "Everything's good right now."

Despite the recentness of the announcement about his diagnosis, the 73-year-old Oscar-nominee said he's been fighting cancer for the last nine years.
