A ground-breaking blood test set to be trialled by the NHS this autumn can accurately detect two thirds of deadly cancers.
The Galleri test, described as the ‘holy grail’ for cancer, detects the disease early in healthy people and NHS officials believe it has the potential to save thousands of lives every year.
Even before someone finds a lump, develops symptoms or visits their GP, early-stage cancerous cells can shed DNA into the bloodstream – which the blood test picks up.

Now results from 4,077 patients in the US show it can detect 67.6 per cent of 12 deadly cancers, including bowel, ovarian, lung and pancreatic.

Overall, it can pick up more than 50 types of cancer. The results come as the NHS prepares to roll out the test to 140,000 people aged 50 to 77 with no cancer symptoms. Another 6,000 with suspected symptoms will be offered tests to speed up their diagnosis.
Each test, together with laboratory analysis which produces a result in around ten working days, costs $949, or around £620, in the US.
It is not known how much the NHS has paid for its pilot. The results are expected in 2023 and, if successful, the test will be made available to around a million people in 2024 and 2025.
The latest results, published in the journal Annals of Oncology, come from trials on 2,823 people with cancer and 1,254 who were cancer-free.
The test wrongly diagnosed people less than 1 per cent of the time – for just six people. For pancreatic cancer, one of the biggest killers because it is usually caught late, the test detected the disease 86.6 per cent of the time.
