New Prostate Cancer Screening Advice: Why Most Men Will Not Be Tested

Prostate cancer is the most common cancer among men in the UK, with over 64,000 cases diagnosed every year. Because of its high prevalence, many people have called for a national screening programme. However, the UK National Screening Committee (UKNSC) has recently released final recommendations that suggest only a very small group of men should be regularly tested for the disease. The committee concluded that for the general population, the harms of screening are greater than the benefits.

Screening involves testing healthy people for a disease before they show any symptoms. For prostate cancer, this process usually starts with a blood test known as the prostate-specific antigen (PSA) test. If the results are concerning, doctors may follow up with an MRI scan. The goal is to find cancer early when it is easier to treat. However, the UKNSC noted that current testing methods are not reliable enough to support a national programme. According to the BBC, the committee found that for every 1,000 men in their 50s who are screened, only two lives would be saved over 15 years. In contrast, 20 men would be told they have a cancer that might never have caused them any problems.

This issue of "overdiagnosis" is a major concern for medical experts. Many prostate cancers grow very slowly and would never become a threat to a person’s life. If these cancers are found through screening, men often undergo treatments that can cause long-term damage. These treatments can lead to serious side effects, such as incontinence — the inability to control one's bladder — and erectile dysfunction. Prof Sir Mike Richards, who chairs the screening committee, explained that doctors still cannot reliably tell which cancers need treatment and which do not. Because the available treatments can cause lasting harm, the committee believes that screening healthy men does more damage than good.

Many people had hoped the committee would recommend screening for all high-risk groups. This includes black men, who are at twice the risk of developing prostate cancer compared to others, and men with a family history of the disease. However, the committee decided against this. According to The Guardian, the UKNSC stated there is still too much uncertainty regarding whether screening would truly help these groups. They noted a lack of clear evidence from clinical trials to support a wider programme. This decision is expected to be disappointing to many, including high-profile campaigners like Sir Chris Hoy and former prime minister David Cameron, who have spoken publicly about their own experiences with the disease.

Despite the strict advice against general screening, the committee did identify one specific group that should be tested. Men who carry a BRCA2 gene variant and have a family history of breast, ovarian, pancreatic, or prostate cancer are at a much higher risk. In this group, the cancer tends to develop earlier and grow more aggressively. For these men, the benefits of early detection are considered strong enough to justify the risks of screening. The committee recommends that these individuals be invited for a PSA blood test every two years between the ages of 45 and 61. This group represents only a few thousand men across the country.

Looking ahead, the committee emphasized that their advice is not permanent. They plan to continuously evaluate new evidence as it becomes available. This includes new testing technologies, the use of artificial intelligence, and the results of ongoing research, such as the Transform trial. These future developments might eventually provide better ways to distinguish between harmless and dangerous cancers. For now, however, the official recommendation remains focused on protecting the majority of men from the physical and psychological burdens of unnecessary medical intervention.
