Prostate Cancer Screening Guidelines

Age-Based Recommendations

For average-risk men, the American Cancer Society recommends PSA screening discussions to begin at age 50 if life expectancy is at least 10 years 1, 2
The National Comprehensive Cancer Network recommends African American men to begin PSA screening discussions earlier at age 45 due to higher risk of aggressive disease 3, 2
Men with a family history of prostate cancer should start discussions at age 45, according to the National Comprehensive Cancer Network 3, 2
The National Comprehensive Cancer Network recommends initiating PSA screening at age 45 for all men 3, 2

PSA screening in men aged 55-69 years may prevent approximately 1.3 deaths from prostate cancer per 1,000 men screened over 13 years, according to the American Cancer Society 1
Overdiagnosis of indolent cancers that would never cause symptoms is a harm associated with PSA screening, as noted by the National Comprehensive Cancer Network 3
Psychological distress from false positives and diagnosis is a potential harm of PSA screening, as reported by the BMJ 4, 5

Cost-effectiveness is optimized with screening every four years between ages 55-69 and offering active surveillance to men with low-risk disease, according to the BMJ 4, 5
PSA levels can be affected by medications and recent activities, such as finasteride, dutasteride, vigorous exercise, or ejaculation within 2 days, as noted by the BMJ 4, 5

The BMJ recommends avoiding PSA testing within 2 days of vigorous exercise or ejaculation to prevent false positive elevations 4, 5
Prostate biopsy is usually performed transrectally with ultrasound guidance and requires antibiotic prophylaxis, as described by the BMJ 4, 5

Refrain from vigorous exercise for 48 hours before testing, particularly cycling or activities that may mechanically stimulate the prostate 6
Avoid ejaculation for 2 days (48 hours) before PSA testing to prevent transient PSA elevations 6
Be aware that 5-alpha reductase inhibitors (finasteride, dutasteride) can lower PSA levels by approximately 50% 6
If medically possible, avoid transient medications such as NSAIDs, stimulants, antihistamines, antibiotics, and cold medications for at least 24 hours before testing 7

Confirm there is no active urinary tract infection or prostatitis, as these can artificially elevate PSA 8
If PSA is initially elevated, it should be confirmed after a few weeks under standardized conditions (no ejaculation, manipulations, or urinary tract infections) in the same laboratory 8

PSA testing can be performed at any time of day, though early morning is preferred for consistency 7
No fasting is required for PSA testing 6
Habitual food and caffeine intake are of no concern and do not need to be restricted 7

A limited PSA elevation should be confirmed after a few weeks under standardized conditions before proceeding to further testing such as biopsy 8
This confirmation test should also follow the same 48-hour restrictions on exercise and ejaculation 6
