Wow! That's scary!

In an interview on SiriusXM's The Howard Stern Show, Ben Stiller revealed that two years ago he was diagnosed with prostate cancer at the age of 48.

The 50-year-old revealed the shocking news on Tuesday, explaining that his doctor was able to catch and treat the cancer.

"It came out of the blue for me. I had no idea," Stiller explained to Howard Stern. "At first, I didn't know what was gonna happen. I was scared. It just stopped everything in your life because you can't plan for a movie because you don't know what's gonna happen."

The Zoolander actor also explained his decision to announce his cancer battle was to help other men."I wanted to talk about it because of the [PSA] test ... I feel like the test saved my life," revealed the funny man.

The PSA test, aka prostate-specific antigen test, is a blood test used to screen males for prostate cancer, which is, "The second most deadly cancer, but it's about one of the most curable," according to Stiller.

When the actor was first diagnosed, he made a call to his Meet the Parents co-star who beat prostate cancer several years ago. Stiller said, "The first thing I did when I got diagnosed was get on the internet to try to learn. I saw De Niro had had it. I called him right away."

Stiller and wife Christine Taylor told their two children, daughter Ella, 14, and son Quinlin, 11, about what was going on. "I told them I had something I had to deal with," he said. "They were pretty cool with it."

We're glad Stiller is okay and has pulled through. The Emmy winner said to Stern that he has a new lease on life, "Afterwards, it just gives you an appreciation for life ...Every six months I'm taking my PSA test to make sure I'm clear."
