PSA testing is done for the early detection of prostate cancer.
However, an abnormal PSA is not specific for prostate cancer alone. There are other causes of an abnormal PSA such as:
- Enlarged benign prostate (BPH)
- Urinary tract infections
- Recent ejaculation etc.
The risk of prostate cancer depends on how abnormal the PSA is. For example,
- Risk of prostate cancer for PSA 4-10ng/ml—around 25%,
- Risk of prostate cancer for PSA 10-20, around 33-50%.
The risk of cancer increases as the PSA increases.
I would suggest that you see a urologist for further assessment. If there are no other obvious causes of an abnormal PSA, further tests may be offered to check for prostate cancer. This includes an MRI of the prostate and/or a prostate biopsy.
