Prostate Cancer: What Does My Low PSA Test Score Mean? More info: http://bit.ly/xHZ0qH When screening for prostate cancer, even a low PSA score can mean you're at increased risk for the disease. John W. Davis, M.D., assistant professor in the Department of Urology at MD Anderson, explains why. Video transcript: One of the risk factors that showed up on that one slide said that even though your PSA test is low, you might still have prostate cancer. Is there any data that kind of indicate how great a risk that really is? At the most, and I think we've shown the slide at prior meetings so you could look at them on the archive websites, but the test that got our attention was a screening trial where men got put on a preventative agent versus a, you know, placebo or dummy pill. And then at the end of the trial, everybody got a biopsy. And it was actually one of the first trials where we had several thousand men with what we considered low PSA's get a biopsy anyway. And that's why a lot of us have lowered the PSA threshold. So even for PSA between 2 and 3, you're seeing cancer detection rates in the 20 percentile. And really even if the PSA was 1 to 2 or less than 1, you still had detection rate. So there was no normal PSA and any group of men that got diagnosed, you know, a small percentage of them had high grade cancer even. So it's a range of risk and that's part of, you know, the education process. Video description: John W. Davis, M.D., assistant professor in the Department of Urology at MD Anderson discusses how a low PSA score does not mean you are risk free from developing prostate cancer at the 2011 Prostate Health Conference, "Protect Your Prostate: Get the Facts," September 10, 2011, Houston, Texas. Davis chairs this educational conference for healthy men and those with prostate cancer, as well as their families. The Prostate Health Conference updates men on current issues in prostate health, prostate cancer, screening, the PSA test, treatment, research, education and prevention. Prostate cancer is the most common cancer among men in the United States, and more than 192,000 cases are diagnosed each year. More than 2 million men in the United States, one man in every six, have been diagnosed with the disease. View the complete 2011 Prostate Health Conference: http://bit.ly/y10drf
