In the USA, they developed a test capable of determining 50 varieties of cancer, it was called the Gallery test. In 2021, it will begin to be tested in humans, 165 thousand patients will be invited to participate. If the testing is successful, a million people will receive the test in the next five years.
The test is able to detect cancer even before the disease manifests itself, writes The Daily Mail. Accordingly, it will be possible to start treating earlier, and the chance of a positive outcome will be higher. Testing will be carried out on blood through the DNA that the tumor releases.
The executive director of the British National Health Service, Simon Stevens, believes that the test will be especially useful in cases where cancer cannot be diagnosed. In addition, the test is able to accurately indicate where the tumor is in the body.
This year, testing was carried out on 1,200 patients, the test accurately worked in 96% of cases, in 1% of cases the result was erroneous. With individual cancers, the test has not been good enough.
