Jane Ghosh recently questioned why the NHS imposes upper age limits on routine screening for bowel and breast cancer (Letters, 28 April). The rationale is that screening, which involves testing based on risk rather than symptoms, is discontinued when the likelihood of benefit is outweighed by the potential for harm. Diagnostic testing, however, remains available at any age.
Expert Clarification
Dr John Doherty from Stratford-upon-Avon, Warwickshire, explains that the threshold is set where the chance of helping an individual drops below the chance of causing harm. This ensures that resources are focused on those who stand to gain the most from early detection.
Requesting Tests Beyond the Age Limit
In response to Jane Ghosh's concerns, David Duell of Durham points out that individuals over the age thresholds can still request a bowel cancer test every two years or breast cancer screening every three years. The challenge, he notes, lies in remembering to do so.
