Former Sky News presenter Dermot Murnaghan has revealed his stage-four prostate cancer diagnosis and is now urging men to take PSA testing seriously. Speaking on Sky News, he explained that he had no obvious warning signs—such as urinary changes or blood in the urine—before suddenly becoming unwell while abroad. On returning to the UK, he was diagnosed with advanced prostate cancer.
Murnaghan admitted he had delayed having a PSA (prostate-specific antigen) test despite knowing the risks: “Life intervenes—jobs, children, holidays—and I kept putting it off. Then came a real bolt from the blue.” He is now calling on men, especially those over 50 or with a family history of the disease, to be proactive and request a PSA test.
Why PSA Testing Matters
The PSA test is a simple blood test that measures the level of prostate-specific antigen in the blood. Raised PSA levels can be a sign of prostate problems, including cancer. While the test was once debated, improvements in accuracy mean PSA testing is now a valuable tool for early detection. As Murnaghan highlighted, catching prostate cancer early through a PSA test is better not only for patients but also for the healthcare system. Treating advanced disease is complex, costly, and demanding, while early treatment guided by PSA results can often be straightforward and highly effective. Unlike breast or cervical cancer, there is no national NHS screening programme for prostate cancer. Men must actively request the PSA test.
Symptoms of Prostate Cancer
Prostate cancer often develops silently, with symptoms appearing only when the disease has grown or spread. Possible warning signs include:
- Difficulty starting urination or straining
- Weak or stop-start urine flow
- Frequent or urgent need to urinate, especially at night
- Feeling that the bladder isn’t fully empty
- Erectile dysfunction
- Blood in urine or semen
- Unexplained lower back pain or weight loss (advanced disease)
Even without symptoms, PSA testing can provide vital reassurance or allow early detection.
Rising Cancer Cases in England
Murnaghan’s message about PSA screening comes as cancer charities warn of a steep rise in cases. One Cancer Voice, a coalition of more than 60 charities, estimates that by 2040 there could be over six million new cancer diagnoses in England—a new case every two minutes. This makes early PSA testing and rapid diagnosis more important than ever.

Frequently Asked Questions
What is a PSA test?
A PSA (prostate-specific antigen) test is a simple blood test that measures the level of PSA protein in your blood. Elevated levels can indicate prostate cancer, but also other prostate conditions such as an enlarged prostate or infection.
Who should have a PSA test?
Men over 50 are encouraged to consider a PSA test. If you have a family history of prostate cancer or are of African or Caribbean heritage, your risk is higher, and testing may be recommended earlier (from age 45).
Does a raised PSA always mean cancer?
Not always. A raised PSA can also be caused by non-cancerous conditions such as prostatitis (inflammation) or benign prostate enlargement. That’s why it’s important to discuss results with a GP who can arrange further investigations if needed.
How often should PSA testing be done?
There is no single rule. Many men choose to repeat the PSA test every 1–2 years, especially if they have risk factors. Your GP can advise on the most appropriate interval for you.
Is PSA testing available on the NHS?
The NHS does not offer routine prostate cancer screening. However, men can request a PSA test through their GP. At OneMedicine, we offer rapid access to same day PSA testing with same day results explained clearly by an experienced doctor.
