In a significant shift in public health policy, the UK's National Screening Committee has recommended that only men at the highest risk of prostate cancer should be offered screening. This targeted approach aims to avoid the potential harms associated with widespread testing, which experts argue could outweigh the benefits for the majority of men.
Targeted Screening for High-Risk Groups
Prostate cancer affects approximately one in eight men in the UK and claims over 12,000 lives annually. Despite its prevalence, the NHS currently lacks a national screening programme. The new recommendations propose screening only for men aged 45 to 61 who carry a pathogenic variant of the BRCA2 gene and have a family history of breast, ovarian, pancreatic, or prostate cancer. This narrow criteria means only a few thousand men would be eligible.
Why Not Wider Screening?
The committee concluded that a broader programme would "do more harm than good." Many prostate cancers grow so slowly that they would never become life-threatening, but a diagnosis can still cause significant anxiety and lead to unnecessary treatments. These treatments often carry side effects such as urinary incontinence, erectile dysfunction, and bowel problems. The committee's modelling suggests that out of 1,000 men aged 50-60 screened, around 28 would be diagnosed with cancer, but approximately 20 would be overdiagnosed and 12 would receive unnecessary treatment. Only about five would genuinely need treatment, and screening could save up to two lives.
Screening Process and Future Prospects
Screening begins with a PSA blood test, followed by an MRI or other tests if results are abnormal. While the current recommendations are limited, the committee noted that advances in technology and understanding could enable wider screening in the future. Health ministers across the UK will now decide whether to implement these recommendations.
Currently, any individual with a prostate can discuss the pros and cons of a PSA test with their GP, and some may be offered it during routine check-ups. Prostate Cancer UK encourages men to have informed conversations with their doctors about the risks and benefits.
