Three years after losing the love of his life due to cancer, the deadly disease has come back to hit Love Story star Ryan O'Neal. But this time, the actor is sure to fight it back.

Best known for his role in ABC's Peyton Place, the actor has confirmed to People magazine that he is diagnosed with stage four prostate cancer.

Recently I was diagnosed with stage 4 prostate cancer, he said in a statement.

The 70-year-old actor, though cancer stricken at the moment, seems to be in a good condition and was reportedly seen taking a stroll on a beach of Malibu along with his dog.

O'Neal further told the magazine that since the cancer was detected at an early stage, it was possible for him to recover completely.

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, he added.

O'Neal lost his long time love Farah Fawcett three years ago after she lost battle with anal cancer. He has been working on a book about the years they spent together. Both of Us is set for release May 1.

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

Fawcett and O'Neal had one child together, Redmond O'Neal. Fawcett  died at the age of 62.  O'Neal has three other children, including his actress daughter Tatum.

Earlier also, O'Neal faced health issues. In March 1998, the actor was diagnosed with chronic myelogenous leukemia and has been in remission since 2006, according to Us Weekly.
