This might seem to be away from my usual topic of mental health, but, as a GP, I see patients get ill with prostate cancer, but also how the harms of treatment for prostate cancer affect both physical and mental health, and I know that many of the men affected never needed to go on that cancer journey- their cancer would have been so slow growing that they would never have known they had prostate cancer if it hadn’t been for the PSA test, and they would have been fine.
If you have had prostate cancer picked up through screening, then of course you will assume you might have died if it hadn’t been picked up early, and if someone you know has died of prostate cancer then of course it is natural to assume they would have lived if only there had been a screening programme. But screening for cancer is more complex than it seems - some cancers evade the screening test and break through anyway while (especially with prostate cancer) the idea that we should always pick up cancer early isn’t always right - in reality, the majority of prostate cancers picked up on screening are picked up far too early and most would be better not known about. This is why only proper clinical trials can tell us about the harms and benefits of screening, and that is what the screening committee will have looked at.
As a GP I see the full impact of how people can and still do die from cancer, but I also see the enormous impact, physically, emotionally and socially, of being put on the cancer journey, and I would like to see both fewer people die from cancer and fewer people go on that journey unnecessarily.
I really celebrate the fact we have a screening committee in the UK that can look at these tough decisions. It is vital that they are free from the influence of politicians, lobby groups and celebrities and can make these difficult decisions based purely on the evidence of harm versus benefit.
In the meantime, if a man still wants to be screened they can still ask their GP for a PSA test, but it might help him to read the report from the UKNSC first, or the excellent advice provided by Cancer Research UK.
