What is PSA? Your Complete Guide
PSA is a protein made by the prostate gland. It's used as a screening tool for prostate health, but elevated levels do NOT automatically mean cancer — many benign conditions can raise it too.
💡Simply Explained
PSA is like a smoke detector for the prostate. Just like a smoke detector can go off because of burnt toast (not a real fire), a high PSA can go off because of many harmless reasons — not just the serious ones.
📏Normal Range
Typical reference range. Your lab may use slightly different values.
⬆️What High PSA Means
Possible Causes
- Benign prostatic hyperplasia (BPH) — enlarged prostate
- Prostatitis (prostate infection or inflammation)
- Urinary tract infection
- Recent ejaculation or vigorous cycling
- Prostate cancer (only one of many causes)
Foods That Can Help
- Tomatoes and tomato-based curries (lycopene is prostate-friendly)
- Pomegranate juice
- Green tea
- Pumpkin seeds (kaddu ke beej)
- Cruciferous vegetables like broccoli and cauliflower (gobi)
⬇️What Low PSA Means
Possible Causes
- Not clinically significant
Foods That Can Help
- Not clinically significant
🏃Lifestyle Actions
If Your PSA Is High
- Do NOT panic — most mildly elevated PSAs are not cancer
- Get a repeat test in 4-6 weeks (avoid ejaculation and cycling 48 hrs before)
- Ask your doctor about free PSA ratio or PSA velocity
- Consider a urology referral if PSA is persistently elevated
- Stay physically active — regular exercise supports prostate health
If Your PSA Is Low
- Not clinically significant
🩺When to See a Doctor
High PSA
If PSA is above 10 ng/mL, see a urologist promptly. Between 4-10, get a repeat test and free PSA ratio — most causes are benign. A rapidly rising PSA over months is more concerning than a single elevated reading.
Low PSA
Low PSA is normal and requires no action.
🎯Did You Know?
The prostate gland is about the size of a walnut, but it can grow to the size of a lemon as men age — and that growth alone can raise PSA without any cancer being present!
