PSA Testing Should Be Discontinued in a 75-Year-Old Man
For a healthy 75-year-old man, PSA screening should generally be stopped, as the harms substantially outweigh any potential benefits at this age. 1, 2
Guideline Consensus Against Screening at Age 75
The major guideline organizations are remarkably consistent on this point:
- US Preventive Services Task Force (2018): Recommends against screening for men aged ≥70 years 1, 2
- American College of Physicians (2013): Recommends against screening in men aged ≥70 years 3
- American Urological Association (2015): Recommends against routine screening in those with life expectancy <10-15 years 1
- European Association of Urology (2018): Recommends against screening for men with life expectancy <15 years 1
The only exception is the US National Comprehensive Cancer Network, which suggests continuing screening beyond 75 years "with caution" only in exceptionally healthy patients with little or no comorbidity 1.
Why Screening Should Stop at 75
The rationale is straightforward and evidence-based:
Increased Harms in Older Men:
- Higher rates of false-positive results requiring unnecessary biopsies 2
- Greater complication rates from both diagnostic procedures and treatments 4
- Substantially increased overdiagnosis—detecting cancers that will never cause symptoms or death 3, 2
Minimal to No Benefit:
- Competing mortality risks from other causes far exceed the risk of dying from prostate cancer 4
- The median age of death from prostate cancer is 80 years, and many men never experience symptoms 2
- Any potential mortality benefit requires 13+ years to manifest, making it irrelevant for most 75-year-olds 2
Treatment Complications Are More Severe:
- 1 in 5 men develop long-term urinary incontinence after radical prostatectomy 2
- 2 in 3 men experience long-term erectile dysfunction 2
- These rates are even higher in elderly patients 4
The Rare Exception
If your 75-year-old patient is exceptionally healthy with minimal comorbidities, excellent functional status, and a realistic life expectancy exceeding 15 years, you might consider discussing continued screening. However, this represents a very small minority of 75-year-olds and should not be the default approach 1, 4.
Common Pitfall to Avoid
Do not continue "routine" annual PSA testing simply because the patient has been getting it for years. The evidence clearly shows that screening older men substantially increases overdiagnosis without improving life expectancy 3. The appropriate action at age 75 is to have a conversation about stopping PSA screening, not about continuing it.
