Prostate Cancer Screening: Why the PSA Test Isn't the Whole Story


By The Medical Team 22/07/26


Prostate cancer is the most common cancer in men in the UK, yet screening remains contentious. There's no national programme because the standard PSA test isn't reliable enough on its own. That doesn't mean men are without options it means the approach has evolved. The conversation now centres on risk-based testing that combines PSA with targeted MRI, multi-cancer blood work, and genetic testing.


The PSA test: useful, but not definitive


A PSA (prostate-specific antigen) test measures a protein produced by the prostate. Levels rise from cancer, but also from benign enlargement, infection, or even recent cycling or sexual activity — hence its reputation for false alarms.


Where PSA helps:


  • Simple, quick, low-cost blood draw
  • Clearer role in high-risk men (family history, genetic mutations, Black ethnicity) for catching aggressive disease earlier
  • Useful for risk stratification when combined with other information

Where PSA falls short:


  • A raised PSA doesn't confirm cancer — most raised results aren't cancer at all
  • Misses clinically significant cancers while flagging slow-growing ones that never would've caused harm
  • Acting on unclear results leads to unnecessary biopsies and anxiety


The UK National Screening Committee has moved away from PSA testing for all men, instead recommending an informed conversation about personal risk. For men over 50, that conversation matters. For those with family history or genetic risk, it matters earlier.


MRI: the game-changer in prostate diagnostics


The most significant shift in prostate diagnostics over the past decade has been using MRI before biopsy, not after. Multiparametric MRI can identify suspicious areas with enough precision to spare many men an invasive biopsy entirely. Those who do need one can have it targeted directly rather than done blind.


At The Private Doctors, prostate imaging sits within our Full Body MRI assessment — gender-specific pelvic imaging alongside detailed views of the brain, spine, chest, and abdomen. One appointment covers considerably more ground than a standalone scan, with zero radiation exposure.


The key distinction: PSA tells you if a signal is present. MRI tells you where to look. Together, they give far more clarity than either alone.


TruCheck: a different signal


Where PSA and MRI target the prostate, TruCheck works differently. It's a blood-based multi-cancer test detecting circulating tumour cells across more than 70 solid organ cancers — 88% sensitivity, 96–99% specificity.


TruCheck isn't a replacement for PSA or prostate MRI. It sits alongside them as a broader early-warning system, particularly valuable for men wanting reassurance across multiple cancer types rather than investigating organ by organ. For men with no specific prostate concern but general interest in proactive screening, it's often the natural starting point — with MRI or prostate-specific testing to follow if needed.


BRCA: the genetic piece men rarely discuss


BRCA1 and BRCA2 are known for breast and ovarian cancer risk, but both carry real implications for men — and BRCA2 is associated with meaningfully higher risk of aggressive, early-onset prostate cancer.


Research from the IMPACT study presented at the European Society for Medical Oncology in 2025 found:

  • Men with BRCA1 face more than 3× the risk of aggressive prostate cancer
  • BRCA2 carriers face more than 2× the risk, diagnosed around five years earlier than non-carriers


On this evidence, researchers are calling for annual PSA testing in BRCA1 and BRCA2 carriers from age 40 — a full decade before general screening conversations typically begin.


Our Genetic Cancer Risk assessment analyses 31 clinically relevant genes (including BRCA1, BRCA2, ATM, and HOXB13) from a single saliva or blood sample, alongside genes linked to breast, bowel, pancreatic, and skin cancers.


For men with family history of prostate, breast, or ovarian cancer, genetic testing should come before the broader screening conversation — because knowing your genetic risk changes when and how often other tests matter.


How to approach this


No single test tells the whole story.


A sensible, risk-adapted approach:


Family history of prostate, breast, or ovarian cancer, or Ashkenazi Jewish descent → Start with genetic testing

BRCA1/BRCA2 positive, or over 40 with other risk factors → PSA testing becomes more valuable, more frequent

Raised or borderline PSA, or want to avoid unnecessary biopsy → Prostate MRI to clarify next steps

General preventative interest, no specific concern TruCheck as a broad first check, with targeted follow-up if indicated


The right combination — and the right frequency — depends on individual risk. That's what a proper consultation is for.

For business owners and directors


If you run a limited company, prostate and cancer risk screening can be funded through the business. HMRC permits one health check-up per employee, per year, without it being treated as a benefit in kind — no personal tax liability, fully deductible for the business.

  • Do I need all four tests, or can I pick one?

    Start with one or two based on your risk profile — genetic testing and/or TruCheck are good entry points for most men. Your doctor will recommend follow-up testing based on those results.

  • What are the prices?

    Genetic Cancer Risk screening — £950 Analyses 31 clinically relevant genes for inherited cancer risk


    Full Body MRI (including prostate imaging) — £1,695 Structural health assessment with gender-specific pelvic imaging, zero radiation


    TruCheck multi-cancer blood test — £1,495 Blood-based detection across 70+ solid organ cancers


    Foundation/Advanced/Executive Health Assessment — from £950 Comprehensive preventative screening tailored to your risk

  • How long does each test take?

    PSA blood draw: 10 minutes. TruCheck blood draw: 10 minutes. Full Body MRI: 45 minutes. Genetic testing: 5 minutes (saliva or blood sample).

  • If my PSA is raised, do I automatically need an MRI?

    Not necessarily. Borderline results often benefit from MRI before biopsy to avoid unnecessary invasive procedures. Your doctor will advise based on your specific result and risk factors.

  • How quickly do I get results?

    PSA and TruCheck: 7–10 days. Genetic testing: 2–3 weeks. MRI: typically within a week. You'll then have a consultation to discuss findings with a doctor.

  • Can I do these tests on the same day?

    Yes. Blood tests (PSA, TruCheck, genetic) can all be done together. You can also schedule an MRI on the same visit if you prefer.

  • How often should I be tested if I'm at higher risk?

    This depends on your risk profile and previous results. BRCA carriers are advised annual PSA testing from age 40. Men with family history typically benefit from testing every 1–2 years. Your doctor will set a schedule that makes sense for you.

  • What happens if something is flagged?

    You'll have a follow-up consultation to discuss the finding, potential next steps, and specialist referral if needed. We can arrange this quickly.

  • Is this covered by private health insurance?

    Many policies cover preventative screening, but coverage varies. We can advise on your specific policy and help with claims if applicable.
