What can raise PSA besides cancer
PSA is produced by prostate tissue, not by cancer specifically, so anything that irritates or enlarges the gland pushes the number up.
- Benign prostate enlargement — by far the commonest reason
- Urine infection or prostatitis
- Recent catheter, cystoscopy or urinary retention
- Long cycle rides or recent ejaculation before the test
- Laboratory variation between different assays
The modern pathway
Rather than biopsying every raised PSA, current practice repeats the test after treating any infection, calculates PSA density against prostate volume, and uses a multiparametric MRI to decide. An MRI reported as PI-RADS 1 or 2 with low PSA density often means a biopsy can safely be avoided, with monitoring instead. Where a lesion is seen, the biopsy is targeted to it rather than taken blindly.
What the biopsy involves
Done under local or short general anaesthesia as a day-care procedure. Blood in the urine or semen for a few days afterwards is expected and harmless. Antibiotic cover is given, and the transperineal route lowers infection risk further. Results typically take about a week, and the report gives the Gleason grade group that guides everything that follows.
PSA Screening & Prostate Biopsy — common questions
What PSA level is considered normal?
Under 4 ng/mL is broadly used, but interpretation depends on your age, prostate size and PSA trend over time. A rising value matters more than a single figure.
Should every man get a PSA test?
Discuss it from around age 50, or 45 if a father or brother had prostate cancer. The test is worth doing when you understand what an abnormal result would lead to.
Is a prostate biopsy painful?
Discomfort rather than pain, with local anaesthesia or short sedation. Most men go home a couple of hours later.
Can I avoid a biopsy if my MRI is normal?
Often yes. A reassuring MRI with a low PSA density supports monitoring with repeat PSA instead of immediate biopsy.
