Navigating the Decision to Stop PSA Testing
Determining the appropriate time to stop or continue regular prostate-specific antigen (PSA) testing is a significant health decision for aging men. Unlike many routine screenings, there is no single, definitive age cut-off. Instead, healthcare organizations and medical professionals emphasize a shared decision-making process based on a patient's individual circumstances. This personalized approach considers a variety of factors beyond just chronological age, including overall health, life expectancy, personal preferences, and the potential risks versus benefits of continued screening.
The Shifting Balance of Benefits and Harms
For men between the ages of 55 and 69, the United States Preventive Services Task Force (USPSTF) states that the decision to undergo periodic PSA testing is an individual one. For men aged 70 and older, the recommendations change significantly. This shift is primarily due to two key factors: life expectancy and the nature of prostate cancer in older men. The benefits of screening, such as early detection and treatment of aggressive cancer, become less likely to extend a man's life the older he gets. Meanwhile, the harms of screening, which can include complications from false positives, unnecessary biopsies, and side effects from treatment (e.g., incontinence and erectile dysfunction), become more pronounced.
Life Expectancy as a Key Factor
One of the most critical elements in the shared decision-making process is the patient's remaining life expectancy. The American Cancer Society and other medical bodies advise that men with less than a 10-year life expectancy are not likely to benefit from PSA screening. This is because many prostate cancers grow very slowly, and it can take over a decade for a localized cancer to become a serious threat. A healthy 75-year-old with a long life ahead of him might still choose to continue screening, while a man in the same age bracket with multiple severe health conditions might decide to stop.
Varying Guidelines from Different Organizations
Different medical organizations offer varying guidelines, which can contribute to the complexity of the decision. It's crucial for patients to understand these variations and discuss them with their doctor.

Beyond Age: The Role of Individual Health
For many men, the decision isn't based on age alone but on a broader assessment of their overall health. Chronic conditions, such as severe heart disease or diabetes, can significantly impact life expectancy and the ability to tolerate cancer treatment side effects. A man in his late 70s who is otherwise in excellent health may still be a good candidate for screening, while a man in his early 70s with complex comorbidities might not be. Doctors often use life expectancy calculators to help guide this conversation.
The Importance of Shared Decision-Making
Shared decision-making is the process where a patient and their doctor collaboratively determine the best course of action. This involves the physician providing all necessary information about the pros, cons, and uncertainties of continuing PSA testing, and the patient sharing their personal values, preferences, and health goals. A comprehensive discussion should address potential outcomes, including the possibility of a false positive, the need for further testing, and the implications of an aggressive versus a slow-growing cancer diagnosis. The American Academy of Family Physicians provides resources to support these conversations, emphasizing that routine screening is not universally recommended, especially for older adults.
Understanding PSA Test Limitations
It's also vital to remember that the PSA test has limitations. An elevated PSA level does not automatically mean prostate cancer; it can be caused by benign prostatic hyperplasia (BPH), inflammation, or other factors. Conversely, some men with prostate cancer may have normal PSA levels. Because of these imperfections, relying solely on a PSA number can lead to unnecessary worry, biopsies, and potential overtreatment. This is another reason why a thoughtful conversation about the end of screening is so important, especially when the potential for harm may begin to outweigh the potential benefit.

Conclusion: A Personalized Senior Care Approach
Ultimately, there is no set answer to at what age do you stop doing a PSA? The transition from routine screening to a more individualized approach typically occurs around age 70, but this is a guideline, not a rule. The best path forward involves an open and honest conversation with your doctor, weighing the nuances of your specific health situation, personal values, and life goals. By considering factors like your life expectancy, overall health, and the potential for both benefit and harm, you can make an informed decision that is right for you as you navigate the later stages of life. The focus in senior care is increasingly on personalized medicine, and this is a prime example of its application.
