Ben Stiller reveals he has been diagnosed with prostate cancer

Ben Stiller revealed on "The Howard Stern Show" Tuesday that he's been diagnosed with prostate cancer.

Stiller said he was recently diagnosed following some unusual results from a regular physical, TheWrap reports.

"If I hadn't gotten the test, my doctor started giving it to me at 46, I still wouldn't know," the "Zoolander" and "There's Something About Mary" star said. "I wanted to talk about it because of the test, because I feel like the test saved my life."

Stiller was referring to the Prostate Specific Antigen (PSA) test, which looks for signs of potential prostate cancer.

"The controversy about the test is that once you get treatment for prostate cancer, things can happen: incontinence, impotence," Stiller said. "It's the second most deadly cancer, but it's also one of the most survived cancers, if it's detected early."

TheWrap reports that Stiller has been treated, though it's not clear exactly when or what the current status of the cancer is.
