What is a PSA test for prostate cancer?
A PSA test stands for prostate specific antigen, and it is a test that measures the level of that particular protein in a man’s bloodstream. It is only produced by the cells in the prostate gland. Having a high reading on a PSA test does not mean cancer – it can also indicate an infection or other benign prostate conditions, but it is a possible indicator of cancer. Normal PSA readings are very low. PSA tests can also be used to see if there is a possible recurrence of cancer. The test scores usually come back in readings of nanograms per milliliter of blood. A reading of 2.5 or below is considered low, while 2.6-10 is slightly elevated, 10-20 is moderately elevated, and 20+ is high. If no lumps or abnormalities are detected during the DRE, many doctors choose to wait and then do the test again 6-12 months later. Alternatively, urine and blood tests can be run for signs of infection, and ultrasound or cystoscopy can be used to get a closed look at the prostate and surround tissues. Adv
