He has already survived one serious health scare after beating leukemia.
And Ryan O'Neal has revealed he has another fight on his hands after being diagnosed with stage four prostate cancer.
The 70-year-old Oscar-nominated actor also said his doctors have told him he has a good chance of making a full recovery.
The Love Story star said: '"Recently I was diagnosed with stage 4 prostate cancer.
'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, and I urge everyone to get regular check-ups, as early detection is the best defense against this horrible disease that has afflicted so many.'
Something sounds awfully weird with this quote.
1. Stage IV prostate cancer is curable? I mean, even with a well differentiated tumour, does this make sense?
2. You detected a Stage IV cancer "early"? By what definition is that early?
Anyone who knows better can tell me whether he's right or is Ryan too shocked from the diagnosis to be coherent?
