The debate over the merits of prostate cancer screening by using the prostate specific antigen (PSA) blood test is not likely to go away any time soon. However, the majority of men between ages 50-70 will continue to have blood tests to screen for prostate cancer (PCa). According to experts, more than two-thirds of men with an elevated PSA will not be diagnosed with PCa.[i] For many of them, confusion and uncertainty will linger for several reasons:
- They don’t understand what an elevated PSA means, especially because it might be an indicator of normal prostate enlargement, an inflammation or infection, or simply an artifact of certain activities within 24 hours of the blood draw
- They aren’t aware of the connection between PSA and other risk factors for PCa such as family history or exposure to toxins
- They don’t know how their individual test results are related to any other management plan for their health.
Some portion of these patients will be proactive and seek out information on the internet, in books, or from talking to or blogging with others. Although none of this can replace medical advice from their own doctors, they may find reassuring answers and fact-based education. The risk, of course, especially when talking or blogging with others, is that it’s like the blind leading the blind. A man who shares his own experience with another may be inadvertently contributing false confidence or needless worry.
The person most able to remove doubts, confusion and uncertainty is the patient’s own doctor. It is important that doctors who receive lab results take time to go over them with the patient and explain what the PSA value does and does not mean for each individual. Whether the physician is a family doctor, internist, urologist, whatever—it’s important for doctors to remember that in general patients are rather mystified by numerical values and technical terms. Spending a few extra minutes and using everyday words can make the difference between a lingering mental muddle vs. “Oh, now I get it!”
We owe patients peace of mind and clear understanding. We have better tools and knowledge than ever to explain to men whose PSA is elevated and/or risking what it might indicate and what options they have. We also have less fearsome alternatives than sending patients for an immediate random TRUS biopsy. These include getting a more well-rounded analysis of the PSA blood draw to being with, including PSA, free PSA, and total PSA; putting these values side by side gives better information than a single PSA number.
We do men a favor when we don’t assume they automatically grasp the implications of PSA. We help men best when we offer an explanation, then ask if THEY have any questions—and give them a minute to think about it. In this way, we spare them any uncertainty and deepen their trust in us as professionals.
