(CNN) Actor Ben Stiller revealed on Tuesday he was diagnosed with prostate cancer in 2014. The tumor was surgically removed three months later, in September 2014, and Stiller has been cancer-free since. Stiller shared the news on Howard Stern's Sirius XM radio show, and in an essay posted online. According to Stiller, it was the prostate-specific antigen test, a blood test known as the PSA, that saved his life. He was tested and treated in his 40s. But the American Cancer Society recommends testing start at age 50 for men such as Stiller, who are at average risk of prostate cancer. Men at high risk, including African-American men and those with a father, son or brother diagnosed with prostate cancer at an early age should be screened at age 45, the American Cancer Society recommends.Ben Stiller was diagnosed with prostate cancer in 2014 in his 40sAmerican Cancer Society advises prostate cancer screenings start at age 50Prostate cancer is the second-most common cancer in men in the United States, after skin cancer
