A new national register will keep watch over people known to carry cancer genes. The catch: it can only protect those the system has already found – and a whole generation of older adults was never tested at all.
A world-first register – with a blind spot
In January 2026 the NHS launched something genuinely groundbreaking. The NHS England National Inherited Cancer Predisposition Register is a world-first database that brings together people known to carry faults in around 120 cancer-susceptibility genes.
Those with high-risk changes in genes such as BRCA are flagged for regular, organised screening rather than being left to slip through the gaps.
It builds on the earlier Lynch syndrome register, which has already moved more than 12,000 people into extra bowel-cancer screening.
For people with Lynch syndrome, that surveillance is estimated to prevent bowel cancer in 40 to 60 of every 100 who would otherwise have developed it. Catching risk early, and acting on it systematically, saves lives.
But the register has an inevitable blind spot.
It can only watch over people the NHS has already identified as carriers. If your faulty gene has never been found – because you were never tested – you are invisible to it.
Which raises the obvious question for anyone in that position: how would you ever find out? One route, increasingly, is to test privately – an at-home hereditary cancer test now screens the key genes from a simple swab, without needing a referral or a qualifying family history.
A generation that was never offered the test
That blind spot falls heavily on older adults. Predictive genetic testing as we know it is barely a couple of decades old, and wide public awareness of BRCA testing is younger still.
Many of today’s over-60s passed through their highest-risk years long before a swab or blood test for inherited cancer risk was something a clinician would routinely raise.
Access on the NHS has always been gated, too.
As the NHS explains, you generally only qualify if a faulty gene has already been found in a relative, or if there is a strong, well-documented family history.
Plenty of older people carry only a hazy version of that history – an aunt’s unspecified “women’s cancer,” a grandfather’s bowel cancer nobody talked about – that never quite met the threshold.
The group statistically most likely to be carrying an undiscovered cancer gene is also the group least likely ever to have been offered the test.
Finding out – and making sense of it
A test, though, is only as good as the interpretation around it. Results are rarely a clean yes or no; a “variant of uncertain significance” means little without expert context, and even a clear result lands differently at 65 than at 35.
That is why credible testing is built around a genetic counselling session before and after the swab, so the result is explained, put in context and matched against your own history rather than left to land cold in an inbox.
Why it still matters after 60
There is a stubborn assumption that genetic testing is a young person’s concern – something you do before starting a family, if at all. In later life it still changes at least three things.
First, your own monitoring. Knowing you carry a BRCA or Lynch variant unlocks enhanced surveillance – such as the additional breast screening NICE recommends for women at high risk, or regular colonoscopy for Lynch syndrome – that catches cancer earlier, when it is far more treatable.
Second, treatment.
If cancer does develop, knowing the genetics in advance can steer care: a BRCA result can point towards targeted drugs, and a Lynch diagnosis can open the door to immunotherapy that conventional chemotherapy cannot match. That information is far more useful established calmly beforehand than scrambled for after a diagnosis.
Third, your family. A faulty BRCA gene carries a 50 per cent chance of being passed to each child, and the same odds for each sibling.
Testing in your sixties is rarely just about you – it is often the single most useful thing you can do for your children and grandchildren, who can then be tested and, where needed, monitored from a far younger age.
Knowing is only the first step
None of this helps if the result then sits in a drawer. Its value lies entirely in the follow-through – the enhanced screening, the lifestyle adjustments, and a clinician who keeps the whole picture under review.
For many older adults the quickest way to turn a result into a plan is to sit down with a private GP, who can talk it through, arrange appropriate monitoring and make the right onward referrals.
That is, in effect, what the new register does automatically for the people it already knows about. For the over-60s it has never tested, the first move still has to be their own.
The window the register can’t see
As the population ages, more inherited cancers will surface, and the National Inherited Cancer Predisposition Register will rightly help thousands of them.
But the people it cannot see are, disproportionately, the oldest – the ones who came of age before the testing existed.
For them the message is simple, and easily missed: testing late is still testing in time, both for their own care and for the generations who share their genes.
