An abnormal prostate-specific antigen (PSA) result means that I have prostate cancer
It's a myth!
Several causes other than cancer can explain an increase in prostate-specific antigen (PSA).
The risk of prostate cancer is considered low with an antigen level below 4.0 ng/mL. A result higher than this value may indeed be due to prostate cancer, but it can also be explained by benign prostatic hyperplasia, an inflammation, a digital rectal exam, a recent prostate biopsy, intense physical activity (such as cycling) or an ejaculation 24 hours before the test.
Therefore, your doctor will assess the need for additional examinations by considering all of these factors.
