PSA Levels for Older Men: Normal Ranges
For men aged 70 and older, the definition of a "normal" prostate-specific antigen (PSA) level differs significantly from that of younger men. As men age, the prostate gland naturally grows in size, a condition known as benign prostatic hyperplasia (BPH), which causes PSA levels to rise gradually. This makes age-specific reference ranges crucial for proper interpretation.
While a PSA level under 4.0 ng/mL was once the universal benchmark for normal, medical experts now recognize that this standard is not appropriate for older men. For men in their 70s, a PSA level up to 6.5 ng/mL is often deemed perfectly acceptable, provided there are no other alarming indicators. For some men in their 70s, a level of 7 ng/mL or slightly higher might be considered in the higher-but-potentially-normal range, especially if it remains stable over time.
It is important to understand that a single PSA test result is not definitive. Doctors track changes in PSA over time, a metric known as PSA velocity, to identify a rapidly rising level that could signal a problem. A sudden, sharp increase in PSA, rather than a gradual age-related rise, is more likely to trigger concern and further investigation.

PSA Testing Considerations for Men Over 70
Major health organizations, such as the U.S. Preventive Services Task Force (USPSTF), do not recommend routine PSA screening for men aged 70 and older due to the potential for overdiagnosis and overtreatment. Many prostate cancers in older men are slow-growing and may never cause harm during their natural life span. Treating these indolent cancers can lead to significant side effects, such as urinary incontinence and erectile dysfunction, without extending the patient's life.
However, some organizations, like the American Urological Association (AUA), acknowledge that some men over 70 who are in excellent health and have a life expectancy of more than 10–15 years may still benefit from screening. The decision to screen should be a personalized one, involving a detailed conversation between the patient and their doctor about the potential risks and benefits.

Conclusion
For a 75-year-old male, a "normal" PSA level is not a single, fixed number but rather a range that is higher than for younger men due to the natural aging process and benign prostatic enlargement. A level up to 6.5 ng/mL is often considered within a normal age-adjusted range. However, a doctor's interpretation depends on many factors, including the rate of PSA change over time, the percentage of free PSA, and the patient's overall health and preferences. Given the risk of overdiagnosis and overtreatment in older men, the decision to continue PSA screening should be made through a careful discussion with a healthcare provider, weighing the potential benefits against the risks. A high PSA result warrants additional investigation, but it is not an automatic diagnosis of prostate cancer.
