Studies recommend that men protect against prostate cancer by getting a digital rectal exam and a PSA blood test by age 40 - even earlier if there is a family history of the disease.
However, the U.S. Preventive Task Force has put a cloud over that, by suggesting a false positive could lead to unnecessary procedures.
Dr. Alan Haynes, a urologist at Texas Tech, says understanding your options is his best advice for men.
"What I say to a patient is, this is a useful test. If you want to do it, if you find something, you need to decide if it needs to be treated or not. You need to find out yourself. I tell all my patients, go to the Internet, look at this stuff, learn what you can, come back, let's talk about it. You want a second opinion, let's go get you one. Don't be afraid to ask the question. You have to make a decision about your life," said Dr. Alan Haynes.
PSA screening is a simple blood test that, along with a digital rectal exam, can help find prostate cancer early.
Dr. Haynes said somewhere around age 40, the first screening can give men an important baseline to help measure the difference in later tests.
