Ben Stiller had a cancer scare two years ago and now he wants to raise awareness on prostate cancer.

Stiller, 50, revealed to “The Howard Stern Show how he was diagnosed with prostate cancer at age 48: “It came out of the blue for me. I had no idea.”

The comedic actor had no history of the disease in his family, only becoming aware of the sickness due to a simple blood test (called a PSA test) recommended by his doctor: “If I hadn’t gotten the test, my doctor started giving it to me at 46, I still wouldn’t know… I wanted to talk about it because of the test, because I feel like the test saved my life.”

He went through a series of evaluations before deciding to have his prostate surgically removed, in response to his intermediately-aggressive cancer. Stiller even reached out to some A-list pals such as Robert De Niro, who previously battled the same disease.

At first, the “Zoolander” star kept the news hush: “I didn’t know what was going to happen… I was scared. The one thing that it does is it just stops everything in your life when you get diagnosed with cancer because you can’t plan for a movie – you don’t know what’s going to happen.”

But now he wants to help others prevent a potentially life-threatening cancer: “It’s the second most deadly cancer, but it’s also one of the most survived cancers, if it’s detected early.”
