Ryan O'Neal - a former leukemia patient -- has been diagnosed with prostate cancer.

"Recently I was diagnosed with stage 4 prostate cancer," the 70-year-old actor said in a statement to People on Friday. "Although I was shocked and stunned by the news, I feel fortunate that it was detected early and according to my extraordinary team of doctors the prognosis is positive for a full recovery.

"I am deeply grateful for the support of my friends and family during this time," the statement continued. "I urge everyone to get regular check-ups, as early detection is the best defense against this horrible disease that has afflicted so many."

Ryan's announcement comes just three years after losing his longtime love, Farrah Fawcett, to anal cancer in 2009.
