A new blood test, currently being piloted by the UK’s National Health System, shows impressive results in detecting tumors in the early stages.

Scientists have developed a simple blood test that can detect more than 50 types of cancer before any clinical signs or symptoms of the disease appear in a person.

The test, which was also piloted by the UK’s National Health System in the autumn, was developed for people at high risk of the disease, including patients aged 50 and over. The Test can detect many types of diseases that are difficult to diagnose at an early stage, such as head and neck, ovary, pancreas, esophagus and some blood cancers.


Scientists said the test pinpointed the cancer before any signs or symptoms appeared and had a very low error rate.

The test, developed by the US-based company Grail, explores chemical changes in pieces of genetic code that seep into the bloodstream from tumors. The Test works by examining DNA shed by tumors and circulating in the blood.

The latest study revealed that the test had an impressively high level of accuracy. The scientists analyzed the performance of the test in 2,823 people with the disease and 1,254 people who did not. The Test correctly determined when cancer was present at all stages of the disease, in 51.5 percent of cases, and found an incorrect detection in only 0.5 percent of cases. It also correctly identified the tissue in which the cancer was found in the body in 88.7 percent of cases.


Head of the Glickman Institute of Urology and Kidneys at the Cleveland Clinic in the US and the first author of the study, said: “with early diagnosis of cancer, the likelihood of treatment being successful increases, this is one of the most important opportunities we have. These data, when used in conjunction with existing screening tests, together with multiple cancer detection tests, can have a profound impact on public health.”

Director of the UK’s National Health System Cancer Clinic, said: “this latest study suggests there may be a chance for a cure for the disease. The data is encouraging. We are working with Grail on studies to see how this test will perform in clinics across the UK National Health System.”
