Ben Stiller's prostate cancer diagnosis was "surreal".
The 'Zoolander 2' star - who was diagnosed two years ago and is currently cancer free - admits he never even thought that he could possibly have the disease, admitting it wasn't "on his radar at all".
He said: "It's surreal. It wasn't something I was thinking about. It wasn't on my radar at all. If it wasn't for this test [a PSA test], I don't think I would have had as easy a course of treatment or prognosis that I did have.
"If it was up to me, I would say every guy should get tested after the age of 40, 45, especially if you have a family history. If I hadn't taken this test, I wouldn't have known."
The 50-year-old actor also revealed he had an operation to have his prostate removed and whilst he was told about the side effects, he feels the decision he made was the best for him.
Speaking to Today's Matt Lauer, he said: "When you're confronted with the question of, 'Hey, do you want to live, or do you want to make sure your sex life is the best it can be?,' I opted for wanting to see what happens, and luckily everything's cool."
Meanwhile, Ben previously admitted the diagnosis came "out of the blue".
He shared: "It came out of the blue for me. I had no idea. At first, I didn't know what was going to 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 going to happen.
"I wanted to talk about it because of the [PSA] test ... I feel like the test saved my life. It's the second most deadly cancer, but it's about one of the most curable."
