PSA or Prostate Specific Antigen is a blood test used in screening for prostate cancer. Elevated level of PSA doesn’t mean you are having prostate cancer. It could be elevated in non cancerous conditions like prostate infection / inflammation, urinary retention, enlarged prostate gland size etc.

Most of the labs have normal reference value of PSA less than 4 ng/mL. Generally this is safe reference value. But rarely even at these low values prostate cancer could be detected. So its better to consult your urologist and follow his suggestions.

Risk of cancer increases with the PSA value. Values greater than 100 ng/mL are almost diagnostic of prostate cancer.

4 – 10 ng/mL25%
> 10 ng/mL50%

This test cost approximately Rs 700 – 900 in New Delhi. It is recommended to do PSA every 2nd year after the age of 50 years. If there is family history of prostate cancer (high risk category) then PSA screening test should start at the age of 45 years.

If my PSA level is high?

If PSA level is high you should consult your urologist immediately. He will do digital rectal examination to feel your prostate gland and might advise you for imaging of prostate (Ultrasound or MRI) and prostate biopsy.

Gold Standard to prove or to rule out prostate cancer is Prostate Biopsy. Prostate Biopsy is day care procedure done in 5 to 10 minutes under local anesthesia.

Biopsy results take 5 to 6 days time. It will finally conclude whether cancer is there or not and the type and grade of cancer.

There is no proven natural method like diet or exercise which can decrease the chances of prostate cancer . So the best thing you can do is screen it or detect it at the earliest.

Do this PSA nest at your nearest lab and consult you urologist.
