A high PSA result means your prostate is producing more prostate-specific antigen than expected. It is a reason to look more closely, not a cancer diagnosis. Benign enlargement, infection, recent ejaculation and cycling can all raise PSA. The usual next steps are a repeat test, a check for infection and, if it stays high, a prostate MRI.
This guide, by Dr. Pedro Yelamo Vera, a GP licensed in Spain, explains how to read your result and how PSA testing works in Spain.
- PSA is a protein made by the prostate; a raised level means the prostate needs a closer look, not that you have cancer.
- An enlarged prostate, infection, recent ejaculation or cycling can all push PSA up.
- A high result is usually repeated, then checked with an MRI before any biopsy is considered.
- Spain has no national PSA screening programme: testing is a shared decision with your doctor.
What is PSA?
Prostate-specific antigen is a protein made by the prostate gland. A small amount passes into the blood. Levels rise naturally with age and prostate size, and they can rise for a short time after anything that irritates the prostate.
Why does prostate cancer testing matter in Spain?
Prostate cancer is the most common cancer in men in Spain. The Spanish Society of Medical Oncology (SEOM) and the Spanish Network of Cancer Registries (REDECAN) estimated 32,188 new cases in 2025. Many are slow-growing, which is why testing decisions balance finding serious cancers early against over-treating harmless ones.
What can raise PSA apart from cancer?
- Benign prostatic hyperplasia (an enlarged prostate), very common after 50.
- Prostatitis or a urinary tract infection.
- Ejaculation in the previous 48 hours.
- Long bike rides or other pressure on the area.
- A urinary catheter or a recent procedure on the bladder or prostate.
What happens after a high result?
- Repeat the test after a few weeks, avoiding ejaculation and cycling for two days before.
- Check for infection with a urine test if you have urinary symptoms.
- Look at the trend: previous results matter more than one number.
- Prostate MRI if PSA stays raised. European urology guidance now uses MRI before a biopsy.
- Biopsy only if the MRI or other findings suggest a significant cancer.
Your doctor may also look at free PSA, prostate volume and your family history to judge the risk.
Is PSA screening offered in Spain?
Spain has no national population screening for prostate cancer. In 2022 the Council of the EU recommended that countries evaluate organised programmes based on PSA followed by MRI. Until then, a PSA test is a shared decision with your GP, usually discussed from about 50, or earlier if a father or brother had prostate cancer.
When should you see a doctor soon?
See a doctor promptly if you have blood in your urine or semen, difficulty passing urine, new bone pain or unexplained weight loss. If you cannot pass urine at all, or have a high fever with urinary symptoms, seek urgent care or call 112.
How can an online GP help?
Dr. Pedro Yelamo Vera can review your PSA history, explain what the result means for you and write a referral to urology when it is clinically appropriate. Send your results by eConsult or book a video visit. Examinations and MRI scans are done in person. Related: blood test results.

Frequently asked questions
What PSA level is considered high?
Many labs flag results above about 4 ng/mL, but there is no single safe number. Doctors look at your age, prostate size, previous results and how fast PSA is rising.
Can a high PSA be caused by something other than cancer?
Yes. Benign prostate enlargement, prostatitis, a urinary infection, recent ejaculation, cycling and a urinary catheter can all raise PSA. Most men with a raised PSA do not have prostate cancer.
Should I repeat a high PSA test?
Usually yes. Doctors often repeat the test after a few weeks, avoiding ejaculation and cycling for a couple of days beforehand, and after treating any infection.
Do I need a biopsy if my PSA is high?
Not straight away. Current European guidance uses a prostate MRI first. A biopsy is considered when the MRI or other results suggest a significant problem.
Is PSA screening offered in Spain?
Not as a national programme. You can discuss the benefits and risks of a PSA test with your GP, especially from about 50, or earlier with a family history.
Do some medicines lower PSA?
Yes. Finasteride and dutasteride, used for an enlarged prostate or hair loss, roughly halve PSA. Tell your doctor if you take them so the result is read correctly.
Can an online doctor explain my PSA result?
Yes. Dr. Pedro Yelamo Vera, a GP licensed in Spain, can review your PSA and other results by eConsult or video and refer you to urology when it is needed.
